What is Androgenetic Alopecia?
Androgenetic alopecia, also known as common baldness, is the most common form of hair loss in both men and women.
This type of alopecia is characterized by progressive thinning of the hair that can begin at an early age and is genetic in nature.
It presents differently in men and women, mainly affecting the frontal areas and crown of the head in men, while in women a diffuse thinning is usually seen at the top of the scalp.
Genetic and Hormonal Causes
Role of Androgens in Alopecia
Androgens, specifically dihydrotestosterone (DHT), play a crucial role in androgenetic alopecia.
DHT is a hormone derived from testosterone that binds to receptors in hair follicles, causing progressive shrinkage of these follicles and resulting in thinner hair and eventual hair loss.
This process is more pronounced in individuals with a genetic predisposition to androgen sensitivity.
Associated Genetic Factors
Genetic predisposition is a determining factor in androgenetic alopecia. This condition tends to run in families, and research suggests that multiple genes are involved in its development.
Both the maternal and paternal sides can contribute to genetic predisposition, which explains why baldness can appear in different patterns within the same family.
Symptoms and Patterns of Hair Loss
Symptoms of androgenetic alopecia include a gradual thinning of the hair, a receding hairline in men, and a widening of the central part of the hair in women.
Typical patterns include:
- Men: Recession of the front hairline and thinning at the crown of the head.
- Women: Diffuse thinning along the top of the scalp, without a clearly defined front line.
Diagnostic Methods
Clinical Evaluation and Trichogram
The diagnosis of androgenetic alopecia is made primarily through a clinical evaluation that includes a detailed medical history and physical examination of the scalp.
The trichogram, a test that examines the hair growth cycle, can be used to assess the density and percentage of hair at different stages of growth. This evaluation helps confirm the diagnosis and determine the severity of alopecia.
Current Treatment Options
Topical Treatments such as Minoxidil
Minoxidil is a widely used topical treatment that has been shown to be effective in stimulating hair growth and slowing hair loss.
It is available in different concentrations and is applied directly to the scalp.
It works by prolonging the hair growth phase and increasing the size of the hair follicles.
Oral Treatments and Their Effectiveness
Oral treatments, such as finasteride, are another option for treating androgenetic alopecia.
Finasteride works by inhibiting the conversion of testosterone to DHT, which reduces the activity of this hormone in the hair follicles.
This drug has been shown to be effective in many patients, slowing down hair loss and in some cases promoting growth.
Advanced Therapies such as Laser Therapy and Microneedling
Advanced therapies, such as low-level laser therapy and microneedling, are also used in the treatment of androgenetic alopecia.
Laser therapy stimulates blood circulation in the scalp and promotes hair growth, while microneedling can aid the absorption of topical treatments and stimulate collagen production.
