Hair loss can be distressing, stressful, and sometimes baffling—particularly when the reason isn't clear. Although genetics, stress, and hormonal imbalance are all well-documented villains, one less familiar but significant player in hair health is vitamin D. But what exactly does vitamin D have to do with hair growth? Does a lack of Vitamin D cause hair loss and thinning? Let's explore the science and hear what the expert, Dr Vedant Ghuse, the finest dermatologist near me that you can search for, has to say.
Vitamin D is a fat-soluble vitamin that regulates calcium and phosphate within the body, both of which are necessary to ensure healthy bones, teeth, and muscles. However, aside from bone health, vitamin D is also involved in cell growth, immune response, and the reduction of inflammation.
Studies indicate that vitamin D can be crucial in the development of new hair follicles—the small pores on your scalp where hair emerges. A lack of vitamin D can interfere with this process, which could lead to thinning or loss of hair.
Specifically, research has found that individuals with conditions such as alopecia areata (an autoimmune condition causing hair loss) tend to have lower vitamin D levels. Although further research is required to establish a cause-and-effect relationship, there is increasing evidence that low vitamin D levels are associated with hair loss and reduced regrowth.
According to Dr Vedant Ghuse, a trusted skin specialist in Tilak Nagar, Vitamin D deficiency can be unexpectedly prevalent, particularly in individuals who:
Common symptoms include fatigue, bone pain, mood changes, and—you guessed it—hair loss.
If your hair loss is due to a deficiency, fixing that deficiency may help enhance hair growth. Some individuals see improvements after supplementing, although results can be mixed.
Before going ahead with supplements, it's worth getting your vitamin D levels tested with a quick blood test. If your tests indicate low levels of Vitamin D, your doctor might suggest:
Most healthy adults need a daily intake of 600–800 IU, but those with deficiencies might require higher doses, at least in the beginning. Be sure to heed your doctor's recommendation, however, since excessive amounts of vitamin D can cause health issues as well.
While vitamin D alone may not be a miracle cure for hair loss, it’s certainly a key piece of the puzzle. If you’ve been struggling with unexplained hair thinning, it’s worth checking your levels.
