Thinning hair at the top of the head and thickening hair near the face can be a common pattern of hair loss known as male or female pattern baldness, also known as androgenetic alopecia. This is a genetic condition that affects both men and women, and it is caused by the effects of hormones called androgens on hair follicles.
Androgens are present in both males and females, but they have a stronger effect in males. In androgenetic alopecia, the hair follicles at the top of the head are more sensitive to androgens, leading to miniaturization of the hair follicles and eventual hair loss. At the same time, the hair follicles near the face are less affected by androgens, leading to thicker hair growth in those areas.
Other factors that can contribute to hair loss and thinning include age, stress, nutritional deficiencies, certain medications, and underlying medical conditions such as thyroid disorders or autoimmune diseases.
If you are experiencing hair loss or thinning, it's important to speak with a dermatologist or hair specialist for a proper diagnosis and personalized treatment plan. There are various treatments available for hair loss, including topical or oral medications, hair transplant surgery, and lifestyle changes such as stress reduction and a healthy diet.
