• Male Pattern Hair Loss

Male pattern hair loss usually begins with a stagnation in the temples or a thinning hair image on the crown, and in some cases progresses to a thinning, followed by a complete loss of the upper part. The hair in the nape and over the ear area is rarely shed, but men over seventy may lose hair in the nape. Both the Hamilton and Norwood scales classify Androgenetic hair loss in men. There are three causative factors for androgenic hair loss: genetic predisposition, the presence of androgen testosterone, and the age of the patient. It causes genetically programmed hairs (in the scale regions) to produce thinner and shorter hairs at each new hair cycle. Testosterone reaches the target organ, in which case the hair follicle testosterone, the enzyme 5α-reductase, converts the testosterone into the high-power di-hydro testosterone hormone that causes the above effects and triggers hair loss.

• Female Pattern Hair Loss

Female pattern hair loss shows scattered thinning in the anterior and crown area of the scalp (Ludwig model) and rarely in the neck and sides. The cavities appear wider and the scalp is more pronounced at the front and midpoint of the head.This is a slow and gradual process and rarely covers the area completely.Androgenetic hair loss in women usually begins with puberty, pregnancy or postmenopausal hormone changes and is quite common in women over 80 years of age. Although there is normally no hair loss recognized by this type of hair loss, there are long-term cases of excessive telogen effluvium. Androgenetic hair loss has three causal factors: age, heredity and the presence of testosterone. Postmenopausal thinning is related to estrogen reduction.

• Telogen Stage Hair Loss (Symptomatic, Reflective Hairloss)

The most common type of hair loss in women is acute telogen effluvium (ATE), but when prolonged it is called chronic telogen effluvium (CTE).

• Acute Telogen Stage Hair Loss

Acute telogen effluvium presents a sudden excessive hair loss with a diffuse scattered distribution across the scalp. A large amount of bristles will be seen in the brush and comb, especially when the hair is shampooed and softened. Many hairs will appear small in the examination of the scalp. Also, there will be very short re-growing conical hairs of similar length along the scalp; The length of the bristles depends on the duration of the condition.

• Chronic Telogen Stage Hair Loss

Telogen hair loss is called Chronic if it lasts more than nine months. Chronic telogen effluvium usually begins with a sudden spill caused by trauma, but can sometimes have a gradual onset and a seemingly ambiguous cause. In particular, there is a loss of hair density in longer hair and lengths, and there is also a diffuse thinning of the hair separations. Hair does not reach the usual length, and there are conical hairs that extend again in different lengths along the head. Re-growth with chronic telogen hair loss is still available, but different lengths. Mostly longer hairs will fall, but shorter hairs are also noticeable. The hair will not grow because the growth length is shortened.

• Anagen Stage Hair Loss

Anagen effluvium is a severe hair loss caused by poisoning due to a direct toxic effect in the cells that rapidly divide the hair follicles immediately after chemotherapy or poisoning. Causes hair loss shortly after chemotherapy, but most people grow again soon after stopping treatment.

• Alopecia Areata.

Alopecia areata, which is often the hardest type of hair loss, offers a range of circularly bald areas. They sometimes combine with other bald areas. Alopecia areata, which is often the hardest type of hair loss, offers a range of circularly bald areas. They sometimes combine with other bald areas. The hair follicles are clearly visible, and the earliest bald area usually extends again, often with white hairs in the center of baldness. When hair loss covers the entire scalp, it is called alopecia totalis. Alopecia universalis is called when the whole body is affected.

• Ophiasis

Ophiasic areata is a marginal presentation of alopecia areata and may affect the neck and front and sides of the scalp. This type of alopecia areata may be more permanent.

• Traumatic Alopecia

Traumatic alopecia is often seen in the upper ears of the scalp and sometimes shows hair loss in the crown area as irregular bald areas. In this region, bristle and short-growing hairs will grow again. It is caused by excessive chemical, thermal or physical trauma as well as scalp scratching. Traumatic alopecia is common in Afro-type hair when exposed to any or all of the above hair styling methods for extended periods of time.

• Traumatic Hair Loss

Trichotillomania is a form of self-injurious physical trauma and a form of obsessive-compulsive disorder. They are very common in children and usually grow with habit. However, it is a much more difficult habit to break in adults.

• Scarrıng Alopecia

Scarring alopecia often presents as an irregular, bright, irregular area of the skin, which may be a darker or lighter color than the surrounding itself. Hair follicles are absent and the skin may be atrophic, even elevated and thickened (Keloid). A wound occurs when a wound heals itself after deep tissue damage. The structure of the scar tissue is different from normal skin and does not support normal hair growth. There are three main causes of scarring: chemical causes, infection and autoimmune disease.
