Top 4 Reasons for Hair Loss
Sun
Changes in weather can also cause changes in hair condition. UV radiation destroys the proteins that make up hair. If you plan to spend a lot of time outdoors, get a good protective spray.
Hormones
Hormonal changes are one of the most common causes of hair loss in women. Dihydrotestosterone (DHT) can activate your hair follicle receptors, causing them to shrink and weaken.
Age
About two-thirds of men will experience some hair loss by age 60, and about 70% of women will experience hair loss by age 70.
Stress
Telogen hair loss occurs when your hormonal changes shock the hair growth cycle, causing hair to go into the resting phase.
