Non-scarring Alopecia
MALES
The most common type of hair loss among men is male pattern baldness, known as androgenetic alopecia. This affects up to 80% of men by the age of 80. It is a condition caused by age, genetics and a specific hormone called DHT (dihydrotestosterone) that attacks hair follicles leading to a disruption of the normal hair growth cycle. This disruption causes follicles to shrink and grow at a slower pace, eventually leading to the hair falling out and the pattern repeating itself with other hair follicles in other parts of the scalp. This process can affect the entire scalp, except for the hair at the back and sides of the head, which is not subject to male pattern baldness. This is a genetically permanent zone, which makes it a viable solution to be used for hair transplant surgery.
FEMALES
It is perfectly normal for people to shed 50 to 100 hairs per day. This generally doesn’t cause noticeable thinning of scalp hair because new hair is growing in at the same time that hair is shedding. However, hair loss occurs when this hair growth cycle and shedding is disrupted or when the hair follicle becomes destroyed and replaced with scar tissue. Female pattern hair loss (androgenetic alopecia) is the most common form of hair loss in women. This occurs gradually and is caused by genetics (from either side of the family), age, and the action of a specific male hormone, dihydrotestosterone (DHT). This hormone is found in lesser amounts in women and it preys on the hair follicles, preventing them from receiving vital nutrients for proper hair follicle growth, leading to the hairs shrinking, and resulting in a shorter lifespan. Interestingly, DHT does not need to be elevated to generate hair loss. Estrogen, when lowered as commonly seen in menopause, creates a change in the ratio of male to female hormones, giving an edge to these male hormones. Compounded with the sensitivity of DHT to the hair follicles, heredity can affect the age at which a woman begins to lose her hair, as well as the rate of hair loss and the extent of baldness.
TRACTION ALOPECIA
Traction alopecia is a type of hair loss caused by self-inflicted pressure and pulling on the hair follicles. Traction alopecia usually starts at the hairline and temples and can progress if the stress on the hair follicles continues. Hair loss from traction alopecia can be stopped and reversed if the cause is found and stopped early. If the hair loss continues, it may become permanent and could require hair transplantation if the patient desires new hair. Plano, TX hair restoration surgeon, Dr. Joseph Yaker, will assess the amount of damage and recommend a course of treatment to restore the lost hair.
CAUSES OF TRACTION ALOPECIA
Traction alopecia is caused by continuous, long-term tension and pulling on hair follicles. It is commonly associated with certain hairstyles (braids, weaves, extensions, cornrows, ponytails) but can also be associated with harsh chemicals (dyes, bleaches, straighteners) and straightening irons. Hair damage can be so severe that the hair root is pulled out completely or destroyed to the point where the hair falls out.
TREATMENTS
If the cause of the stress on the hair is stopped soon after hair loss begins, the hair should recover and re-grow on its own. If the stress continues, the hair loss will continue and may become permanent. Some people will simply need to loosen their hairstyles or limit the amount of time they wear a tight hairstyle. Others will need to avoid any causes of traction alopecia completely.
Nonsurgical Treatment
If hair loss from traction alopecia is minimal and caught early, non-surgical treatments such as Minoxidil (brand name: Rogaine®), platelet rich plasma (PRP) with placenta-derived extracellular matrix therapy and low-level laser therapy may be used to help strengthen and regrow hair. If the loss is permanent, this will lead to scarring alopecia, and hair transplantation would be the only treatment option. Dr. Yaker’s HairScan Plan will help track the progress of hair growth every 90 days after starting any form of nonsurgical therapy.
Surgical Treatment
If there is permanent hair loss from traction alopecia, Dr. Yaker can perform Follicular Unit Extraction (FUE) or Follicle Unit Transplantation (FUT), which extracts healthy hair follicles from the back of the scalp and then transplants these follicles to the areas affected by hair loss. Both FUE and FUT use advanced technology and surgical artistry to create fuller hair with a natural look. FUE and FUT provide similar results, the difference is in the way the hair is removed from the back of the scalp.
