The signs of having a healthy scalp.

It's also worth noting that a healthy scalp does not become oily too quickly. The hyperseborrhea , or the excessive production of sebum by the sebaceous glands, is often due to a high level of androgen hormones such as testosterone, which is present in both men and women, although in smaller quantities in the latter.

Testosterone operates under the influence of an enzyme, the 5-α-reductase, to transform into dihydrotestosterone (DHT), which stimulates the activity of the sebaceous glands. Therefore, individuals with highly active 5-α-reductase are more prone to hyperseborrhea. Fortunately, this condition can be controlled through the regular use of purifying treatments.

The absence of dandruff signifies a healthy scalp. The dandruff appears as a result of an acceleration of skin renewal associated with abnormal desquamation. The epidermal cells, not being mature enough, remain clumped together and detach in excessive white clusters, forming dandruff.

Several factors or combinations of factors can cause dandruff, including parasitic colonization by fungi Malassezia, excessive sebum production, or individual susceptibility. The proliferation of dandruff can be reduced with a dandruff treatment.

A quick analysis of the hair follicle can reveal the condition of a scalp. To do this, one simply needs to pluck a hair from the head, making sure not to miss the bulb. If the latter is well-rounded, it's a sign of a healthy scalp. On the other hand, if it's small and shriveled, it could be a case of afolliculitis.

This refers to a benign skin condition in which hair follicles become inflamed due to excessive sebum production, genetic predispositions, or bacterial colonization. Folliculitis typically causes irritation, itching, and lesions on the scalp. After being diagnosed by a doctor, it is treated with topical care or the administration of medications.

It is natural to lose a few hairs every day, as this is part of the natural hair cycle. Each hair has its own life cycle that begins with a growth phase (anagen), continues with a resting phase (catagen), and ends with the loss of the hair (telogen). Generally, we lose between 50 and 150 hairs per day. Beyond this, the loss is considered abnormal and it could be a case of alopecia.

A simple test to identify abnormal hair loss is to run your hand through your hair, spreading your fingers like a comb. If more than ten hairs remain on your fingers, it is likely a case of abnormal hair loss. In this situation, it is recommended to consult a dermatologist who can assess the severity of the hair loss and provide advice.
