A dermatologist specialising in hair has outlined several distinct types of hair loss, each with its own unique indicators. Androgenic alopeciaDr Adel began by explaining that if your hair parting is widening, your ponytail is thinning, and your hairline is receding, you might be experiencing hair loss due to androgenic alopecia. Telogen effluvium is a prevalent form of hair loss triggered by severe stress or bodily changes, and it's a leading cause of sudden hair thinning in women. This condition can be reversed by ceasing to pull the hair back; however, without early intervention, the hair loss could become permanent. If you're concerned about hair loss, it's advisable to book an appointment with your NHS GP to discuss these worries.
