Hair growth usually occurs in a cyclical phase and the three phases of hair growth include Anagen, Catagen and Telogen phase. The hair growth takes place in the Anagen phase while Catagen phase the hair stops grown and Telogen phase the hair reaches its death stage and falls off. The balance between Anagen, Catagen and Telogen phase is important to prevent hair loss and balding.
In order to understand the relationship between Vitamin D and hair loss, it is important to understand the process of hair growth. Hair growth takes place in three different phases,
- Anagen Phase is the phase when your hair grows. At any point in time about 70% of your hairs are in the anagen phase. The duration of this phase is important, since this phase helps replenish hair that is lost during the telogen phase.
- Catagen Phase is the phase when hair growth becomes stagnant. If the catagen phase gets prolonged, hair that fall of are not replaced which in turn increase the risk of balding.
- Telogen Phase is the phase when the hair become old and fall off. If the telogen phase becomes longer than the anagen phase a person may face severe hair loss and balding.
Vitamin D is an important vitamin which keeps the hair healthy and ensures that the balance between the different phases is maintained. Vitamin D deficiency is known to alter the balance between these phases, resulting in shortening of the anagen phase and lengthening of the telogen or catagen phase. This in turn increases the risk of hair loss and may cause balding.
