Hair & scalp concerns
Understanding
hair loss.
A change in your hair can bring a lot of questions. Understanding the possibilities is a useful first step toward knowing what kind of support you need.
The bigger picture
There can be more
than one reason.
Hair naturally moves through stages of growth, rest, and shedding. Changes in health, hormones, or the demands on your body can affect that rhythm. Other conditions act directly on the scalp, the follicle, or the strand.
Several things can happen at once. Increased shedding may make existing thinning more noticeable, while a scalp condition adds discomfort. Your history, the pattern of change, and a closer look at the hair all matter.
The growth cycle
More hair is shedding.
A change in the cycle can release more hairs than usual. A trigger may have happened months before you notice it.
The follicle & scalp
Growth is changing.
Follicles may produce finer hairs, or inflammation may interfere with growth. Some conditions can permanently damage them.
The strand itself
Hair is breaking.
A strand can snap before it reaches its usual length. Breakage can look like thinning, even when hair is still growing.

Hair loss & scalp conditions.
Open a topic for a plain-language explanation and a useful next step. This guide includes concerns we can help assess, along with conditions that need medical evaluation.
Some changes deserve attention sooner. New bald patches, eyebrow loss, scalp pain or burning, or sores with hair loss warrant a prompt medical assessment. Suspected scarring or infection should be evaluated by a dermatologist or physician before cosmetic scalp services.

Gradual thinning & increased shedding
A wider part, a changing hairline, or more hair in the shower can come from different processes. The timing and pattern help guide the next questions.
↑ Back to categories-
Pattern hair loss develops gradually as affected follicles produce finer, shorter hairs. You may notice a widening part, less fullness at the crown, or a receding hairline. It can affect people of any gender, and the pattern is not identical for everyone.
Family history is one clue, but a similar appearance can have another cause. An assessment helps document the changes and whether additional shedding is happening alongside them. Medical options and supportive hair and scalp care can then be considered according to your needs.
-
A stressful event, fever, illness, surgery, rapid weight loss, or another change in health can shift more hairs into their resting phase. The increased shedding often appears two to four months later, which can make the connection easy to miss. Hair tends to shed across the scalp rather than in one defined patch.
Shedding often settles after the trigger is addressed, but some episodes persist or recur. Ongoing shedding deserves a closer look rather than a promise that it will stop by a particular date. It can also occur alongside pattern hair loss.
-
After pregnancy, changing hormone levels can bring a noticeable increase in shedding. This is usually a form of telogen effluvium, not a separate inherited baldness condition. It often becomes apparent a few months after delivery.
Fullness commonly improves over time. If shedding is persistent, you notice distinct bald patches, or your hair has not recovered by your child’s first birthday, speak with a dermatologist. Other contributors may need attention as well.
-
Some cancer treatments and certain toxic exposures can interrupt hairs while they are actively growing. Hair loss may develop quickly and can be more extensive than the delayed shedding seen with telogen effluvium.
The likely course depends on the cause and treatment involved; regrowth is not guaranteed in every situation. Your oncology or medical team should guide care. Any supportive scalp care needs to fit their recommendations and the condition of your skin.

Health, hormones & nutrition
Hair changes can be part of a bigger health picture. These are possible contributors, not conditions that can be confirmed from hair appearance alone.
↑ Back to categories-
Thinning may become more noticeable around menopause or with changes in hormonal medication. Conditions involving androgen hormones, such as polycystic ovary syndrome (PCOS), can also affect scalp hair. Hair changes with age can overlap with inherited pattern loss.
Hair thinning alone does not prove a hormone imbalance. Irregular periods, new facial hair, or other changes are worth discussing with your physician, who can decide whether testing is appropriate. The aim is to understand the whole picture before choosing a plan.
-
An underactive or overactive thyroid can contribute to thinning or shedding across the scalp. The hair changes may occur alongside other symptoms, but they cannot tell you on their own whether your thyroid is responsible.
A physician can assess your symptoms and arrange appropriate blood tests. Addressing a confirmed thyroid condition is medical care; a hair and scalp assessment can help document the changes and inform supportive care alongside it.
-
Not getting enough food or protein, iron deficiency, and certain other confirmed nutrient deficiencies can contribute to shedding. Restrictive eating, rapid weight loss, and problems absorbing nutrients may be part of the history.
This does not mean everyone with hair loss needs supplements. Your clinician can decide which tests or dietary support are appropriate. Taking extra nutrients without a demonstrated need may be unhelpful, and excessive amounts of some supplements can worsen hair loss. Eating difficulties deserve compassionate, qualified support.
-
Some medications can affect the hair cycle, with changes appearing after a medicine is started, stopped, or adjusted. The timing and type of shedding vary. The same symptom can also come from the condition being treated.
Bring an up-to-date medication and supplement list to your assessment. If you suspect a medicine is contributing, talk with the prescriber. Do not stop or change a prescribed medicine on your own to try to improve your hair.
-
A significant illness can trigger shedding. Some ongoing conditions, including systemic lupus and kidney or liver disease, may also be associated with hair changes. Certain infections, including syphilis, can cause hair loss and need specific medical testing and treatment.
Hair loss alone cannot identify one of these illnesses. A careful history helps establish whether medical evaluation should come first. Supportive scalp care cannot replace care for an underlying disease or infection.

Patchy loss & scarring conditions
Some conditions affect the immune system or cause inflammation around the follicle. Similar-looking patches can have very different causes.
Scarring means a follicle has been permanently damaged. Early dermatology care matters because a destroyed follicle cannot grow a new hair. Alopecia areata, listed first, is usually non-scarring.
↑ Back to categories-
Alopecia areata develops when the immune system mistakenly targets hair follicles. It often causes smooth, round or oval patches, but it can also cause more widespread loss. Eyebrows, eyelashes, and body hair may be affected. Extensive forms include alopecia totalis, affecting the scalp, and alopecia universalis, affecting the body.
The follicles are usually not destroyed, but regrowth can be unpredictable. A dermatologist should confirm the diagnosis and guide medical care. Support can also include help with gentle hair care and the emotional impact of visible changes.
-
LPP is an inflammatory condition that can damage follicles and leave permanent areas of hair loss. Some people notice patchy thinning with itching, burning, tenderness, or scale around individual hairs. Discomfort is not present in every case.
This needs prompt assessment by a dermatologist; a scalp biopsy may be needed to clarify the diagnosis. The priority is protecting follicles that remain. Cosmetic scalp services should not delay medical evaluation or be used over an active flare without guidance.
-
FFA is a scarring condition that often changes the front and sides of the hairline. Thinning eyebrows may be an early clue. It can develop gradually and may be mistaken for an ordinary receding hairline.
Arrange a dermatology assessment if you notice these changes, even if the scalp feels comfortable. Early medical care aims to limit further loss. Hair that has already been lost through scarring cannot be restored by routine scalp care.
-
CCCA often begins at the crown and spreads outward. Early signs can include breakage, thinning, or scalp tenderness, although some people have no discomfort. It most often affects Black women, but it can affect others too.
The causes are complex; it should not simply be blamed on someone’s styling choices. Because this condition can cause permanent scarring, early dermatology assessment is important. Gentle handling may be part of care, alongside the medical plan.
-
Discoid lupus is a form of skin lupus that can produce persistent scaly patches, changes in skin color, and scarring. When it affects the scalp, hair may be permanently lost in the affected areas.
It is not the same as every other form of lupus-related shedding. A dermatologist can assess the scalp and decide whether a biopsy or other evaluation is needed. Medical management comes first; supportive care must be appropriate for the skin’s condition.
-
This inflammatory scalp condition can cause recurring pustules, crusting, and patches of scarring hair loss. Several hairs may appear to grow together in a small tuft. It can be uncomfortable and may persist or return over time.
These changes require dermatologist-led care. They should not be treated as simple product buildup or managed only with a scalp cleansing service. Once follicles are scarred, the lost hair cannot regrow from those follicles.
-
This condition causes deeper inflammation around follicles, sometimes with painful lumps or areas that drain. Repeated inflammation can damage the scalp and lead to scarring hair loss.
A physician or dermatologist should assess painful or draining scalp lesions promptly. Avoid squeezing them or trying to exfoliate them away. Medical care takes priority over cosmetic scalp services.

Flaking, irritation & scalp conditions
Scalp symptoms matter even when density looks unchanged. These conditions do not all directly cause hair loss, and flaking alone does not identify the cause.
↑ Back to categories-
Seborrheic dermatitis is a recurring inflammatory skin condition that can cause scalp flaking and irritation, sometimes with greasy-looking scale. Dandruff is a milder, non-inflamed form. Similar flakes can also occur with other skin conditions.
Addressing scalp comfort is worthwhile, but dandruff should not automatically be blamed for visible thinning. If you have persistent irritation, thick crusting, or hair loss as well, an assessment can help identify whether more than one concern is present and whether medical care is needed.
-
Psoriasis can cause defined areas of thickened, scaly skin on the scalp, sometimes extending beyond the hairline. It may itch or feel sore. Inflammation and repeated scratching or picking can be associated with temporary hair loss.
A clinician can distinguish psoriasis from other causes of scaling and recommend appropriate care. Avoid forcefully removing scale. Any supportive scalp routine should be gentle and compatible with prescribed treatment.
-
A scalp that starts itching, burning, or flaking after a product is introduced may be reacting to an irritant or an allergy. Hair color, fragrance, and other ingredients can be involved. A reaction can also occur after a product has been used before without difficulty.
Let your clinician know which products you use and when the symptoms began. Persistent or severe reactions may need a dermatologist’s evaluation and sometimes patch testing. A product reaction and a separate hair-loss condition can occur together.
-
Tinea capitis is a fungal infection, not a worm. It may cause scaly patches with broken hairs or areas of hair loss. Sometimes the scalp becomes swollen and painful. It is especially common in children and can spread to others.
A medical clinician needs to diagnose and treat it. Prescription treatment taken by mouth is generally required; shampoo or a scalp service alone will not clear it. Avoid sharing brushes or hats, and arrange medical care promptly rather than booking a cosmetic scalp treatment.
-
Folliculitis means inflammation around hair follicles. On the scalp it can cause small itchy bumps or pustules that become sore or crusted. Several causes are possible, so the appearance alone does not identify a particular infection.
Ordinary scalp folliculitis is not the same diagnosis as folliculitis decalvans. Persistent, painful, spreading, or hair-loss-associated bumps need medical assessment. Scalp cleansing should not be used as a substitute for finding out what is causing them.

Breakage, tension & early-life changes
Hair can look thinner because strands break, repeated tension affects the roots, or growth differs from an early age. These distinctions change the kind of help that is appropriate.
↑ Back to categories-
Repeated pulling from tight hairstyles, extensions, or other sources of tension can injure follicles. You may notice broken hairs or thinning in the areas being pulled, often around the hairline.
Reducing tension early can help prevent further damage. Longstanding traction can lead to permanent scarring, so persistent thinning deserves assessment. The goal is to find ways of caring for and styling your hair that protect the areas under stress.
-
Recurrent hair pulling can leave uneven patches and hairs of different lengths. Some people notice an urge to pull; others do it with less awareness. This is a recognized condition and deserves a compassionate response.
Hair care alone does not address the pulling behavior. A qualified mental health professional can offer approaches such as behavioral therapy, while a dermatologist evaluates the hair and scalp. Support should focus on reducing distress and protecting the hair without blame.
-
Heat, chemical processing, friction, and some inherited differences can weaken the hair strand. Instead of shedding from the root, hairs may snap and leave uneven lengths. Examples include trichorrhexis nodosa, where weak points develop along a strand, and bubble hair, often associated with heat damage.
A closer look at the strands and your hair-care routine can help distinguish breakage from shedding. Some unusual shaft findings need specialist evaluation. Gentle handling protects new growth, while damaged lengths take time to grow out.
-
In this condition, growing hairs are not held firmly in their follicles and can come away unusually easily. It is most often noticed in children whose hair seems slow to gain length or looks sparse or uneven.
This is an attachment problem around the growing hair, rather than simply a brittle strand. A dermatologist can distinguish it from other causes of childhood hair changes. Do not repeatedly pull at the hair to test it at home.
-
Some people are born with very sparse hair or develop an inherited difference in hair growth or structure early in life. Terms such as congenital hypotrichosis describe reduced hair growth, but they cover a range of different conditions.
A pediatrician or dermatologist should assess persistent early-life changes, especially when there are differences in the skin, nails, or teeth as well. Care depends on the specific diagnosis; it is not accurate to assume every case is purely cosmetic or needs surgery.
