Our scalp and hair are healthy can be judged mainly by the following conditions: oily scalp, itchy scalp, dandruff, and hair loss.

Scalp hair healthy

clogged hair follicles

Excessive sebum secretion can clog hair follicles, leading to folliculitis. Follicle problems can cause hair loss and slow hair growth.

oily scalp

While scalp sebum nourishes and protects the scalp and hair, excessive sebum can irritate the scalp, leading to an unhealthy scalp, resulting in itching and dandruff.

Scalp hair healthy

Itchy scalp

Scalp allergies, characterized by red patches on the scalp, indicate scalp inflammation.

This is caused by factors such as climate, physical condition, oil, and harmful bacteria irritating the scalp, resulting in an itchy sensation.

Dandruff

Oily dandruff

This type of dandruff, caused by oily hair, consists of large, flaky flakes that easily adhere to the scalp and hair, and are yellowish in color.

It’s caused by excess oil irritating the scalp, leading to the proliferation of harmful bacteria, disrupting the skin’s natural flora balance, and resulting in an unhealthy scalp and excessive dandruff.

Dry dandruff

Dry hair often produces small, numerous flakes of dandruff that easily fall onto the shoulders and are whitish in color.

This is due to insufficient sebum secretion, resulting in inadequate nourishment and protection of the scalp,

a loss of the scalp’s protective barrier function, abnormal scalp metabolism, and increased shedding of dead skin, thus leading to a large amount of dandruff.

Hair loss

Check the hair loss is normal physiological or pathological

First, examine the hair density.

Second, use hair analyzer AI machine to examine hair growth within the hair follicles.

Normally, one hair follicle grows 2-3 hairs,when many follicles only one hair, or one follicle two hairs, but one of them is very thin and yellowish, it indicates pathological hair loss.

Finally, it’s necessary to determine whether the hair loss is caused by oily scalp or dry scalp.

If it’s due to excessive sebum secretion, it can clog hair follicles, causing folliculitis and affecting hair growth; this is a precursor to seborrheic alopecia.

The solution lies in controlling scalp oil production.
