Steger D3

Research shows that a lack of vitamin D in your body can lead to hair loss. One role vitamin D plays in stimulating new and old hair follicles.

 When there isn’t enough vitamin D in your system, new hair growth can be stunted. Vitamin D deficiency has been linked to alopecia, the autoimmune condition that causes bald patches on the scalp and other areas of the body. Both men and women can experience alopecia. 

Another studyTrusted Source found that women 18 to 45 years old who experienced alopecia or other types of hair loss had low levels of vitamin D. Reasons for insufficient vitamin D levels include:

• Spending more time indoors
• Wearing a lot of sunscreens
• Not eating foods packed with nutrients.
