Can Too Much Vitamin and Nutritional Supplement Cause Hair Loss?

It is true that taking too much vitamin and nutritional supplement can lead to hair loss. In addition to an excessive amount of selenium, an overconsumption of vitamin A can also cause hair loss. It is best to not exceed the recommended upper limit for vitamins, as it can lead to a variety of health issues. People who think they are experiencing hair loss due to a vitamin deficiency should not self-diagnose and should instead consult a doctor.

A doctor can test for vitamin deficiencies, make dietary recommendations, and suggest other forms of treatment. It is also possible to have multiple types of hair loss at once, so it is important to get an accurate diagnosis. Vitamin A can also have a negative effect on hair if taken in excess. If you take too many retinol-type supplements for an extended period of time, your hair follicles will speed up the growth phase, leading to hair thinning and, in extreme cases, baldness.

The recommended daily dose of vitamin A is 900 mcg for adult men or 700 mcg for adult women (who are not pregnant or breastfeeding). When taken within the recommended values, it is actually beneficial for hair growth and maintenance, as it helps cells reproduce. However, vitamin A is fat-soluble, so any excess will be stored in the body and can lead to toxicity, one of the symptoms being hair loss. Therefore, it is important to consider what form of vitamin A the supplements contain (provitamin A or preformed vitamin A carotenoids) and in what proportion.

If you are struggling with hair loss, instead of focusing solely on your locks, taking a closer look at your lifestyle and making appropriate changes could help you see how your hair's health changes. Creatine does not directly attack hair follicles but it will increase the amount of testosterone in the bloodstream. Micronutrients such as vitamins and minerals play an important role in the normal development of hair follicles and in the function of immune cells. So can protein shakes cause real hair loss? It depends on the ingredients and composition of the shake; many supplements will not cause any alteration to the hair.

To reverse hair loss in these cases, it is possible with the help of a medical professional to reduce and block DHT levels. While the recommended daily value of vitamins can help delay hair loss, consuming too much can be bad. Iron deficiency may also play a role in female pattern hair loss or chronic telogen effluvium. Research shows that vitamin D supplementation can help restore hair loss in patients with these conditions. To avoid any hair loss due to vitamin deficiency, your diet should include nutrients such as vitamin A, vitamin C, vitamin E, iron, magnesium, and zinc.

The treatment of alopecia is an essential aspect of clinical dermatology given its prevalence and impact on quality of life.
