How does methotrexate induce hair loss?
To understand methotrexate induced hair loss, let us first understand the life cycle of a hair. Hair is made by a hair follicle. Each hair has a growth phase known as anagen & a resting phase known as telogen. A hair follicle grows hair for upto 3- 4 years. This is the end of the life cycle of the hair. It falls, the follicle then rests for about 3- 4 months & starts making a new hair. Normally most scalp hair (about 85%) are in the growth phase & only about 100 scalp hair fall every day. Methotrexate triggers a process called telogen effluvium wherein a greater proportion of hairs suddenly enter the resting phase. The hair thus stops growing & fall out.
How can one take care of methotrexate induced hair loss?
