A receding hairline occurs when the hair at your forehead and temples begins to become thinner and moves backward. For men, this is usually part of male pattern baldness, which is known as androgenic alopecia in medical terms. Women can also notice changes in their hairline, but it typically appears as thinning hair instead of a clear receding line.
You might see your hairline starting to look like a “M” or “V”, or you could feel like your hair is getting thinner towards the front. This is something many people experience, and it can begin at any time after puberty for men or after menopause for women.
