In both reported cases, treatment with 50,000 IU vitamin D3 for 6 weeks and 3 months, respectively, followed by 1,000 IU/daily as a maintenance dose, resulted in noticeable hair regrowth and resolved the deficiency state.
How long does it take to reverse hair loss caused by vitamin D deficiency? With proper treatment and consistent vitamin D supplementation, most people begin to notice improvements within 3-6 months.
Research has found that vitamin D interacts directly with hair follicles. When we have enough vitamin D, it helps hair follicles grow and function properly. This signals the anagen (growth) phase, where thick hair is produced. In essence, maintaining sufficient vitamin D is crucial for healthy hair growth.
Hi, I've seen a few trichologists, vitamin D is somewhere between 70+ or upper end of normal range. Ferritin is at least 50 to stop hair loss, 70-100 is optimal. For vitamin D, I used an oral spray to get mine from 21-25 to 50 within months.

Immune Boost: Studies show vitamin D helps the immune system regulate inflammation and fight infections, so you might notice fewer colds or seasonal bugs within the first few weeks.
When your body doesn't have enough vitamin d, your keratinocytes seem to struggle regulating your natural hair cycle, reducing hair growth and increasing hair shedding. With lower vitamin d levels, the anagen (growth) phase of your hair cycle seems to shorten and your telogen (resting) phase seems to lengthen.
There is not enough research to determine whether increasing vitamin D levels can restore hair loss. There are also numerous possible causes of hair loss, and a person may need to address the underlying issue. However, as vitamin D plays a role in hair growth, getting enough vitamin D may be beneficial for hair health.

Vitamin D toxicity, although rare, can occur from high intake of supplements over an extended period. This toxicity can result in a range of health issues, including hair loss, as the body struggles to regulate the nutrient's effects on various bodily systems.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss. Vitamin B2 (riboflavin) is a component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) [22].
In both reported cases, treatment with 50,000 IU vitamin D3 for 6 weeks and 3 months, respectively, followed by 1,000 IU/daily as a maintenance dose, resulted in noticeable hair regrowth and resolved the deficiency state. In both cases, the patients received no other topical or systemic treatment.
Lack of sunlight itself does not cause hair loss, but the lack of vitamin D, which is mostly obtained from the sun, can accelerate your hair shedding. It is commonly thought that vitamin deficiencies cause hair loss, but what they really do is accelerate the hair loss you are already experiencing.
