From the Guidelines
The temples and vertex of the scalp are the areas most likely to thin first in male pattern baldness. This pattern of hair loss is highly reproducible and occurs due to the sensitivity of hair follicles in these regions to dihydrotestosterone (DHT) 1. The hair loss typically begins at the temples, creating an M-shaped hairline, and is accompanied by thinning on the crown of the head. Key characteristics of male pattern baldness include:
- Preferential affectation of the temples, vertex, and mid-frontal scalp 1
- Highly reproducible pattern of hair loss
- Sensitivity of hair follicles to DHT, leading to miniaturization and eventual cessation of hair production
- Preservation of hair on the sides and back of the head due to genetic resistance to DHT's effects. The Hamilton-Norwood classification system is commonly used to describe the patterns of hair loss in males, providing a framework for understanding the progression of male pattern baldness 1.
From the Research
Male Pattern Baldness
- Male pattern baldness, also known as androgenetic alopecia, is a common hair loss disorder affecting up to 80% of males by the age of 80 2.
- It is characterized by androgen-related progressive thinning of hair in a defined pattern.
Area Most Likely to Thin First
- The area most likely to thin first in male pattern baldness is not explicitly stated in the provided studies.
- However, it is known that androgenetic alopecia typically starts with thinning of hair on the scalp, particularly on the top and crown areas 3, 4.
- The exact pattern of hair loss can vary from person to person, but it often follows a specific pattern, such as a receding hairline or thinning on the vertex of the scalp.
Treatment Options
- Various treatment options are available for male pattern baldness, including minoxidil, finasteride, and low-level laser therapy 2, 3, 5, 6.
- These treatments can help slow down or stop hair loss, and in some cases, promote hair regrowth.
- However, the effectiveness of these treatments can vary from person to person, and it's essential to consult a healthcare professional to determine the best course of treatment.
