Over-Supplementation Can Sabotage Your Hair
Yes – more isn’t always better. While vitamins and minerals are essential for healthy hair, taking too much, especially without testing, can backfire.
Piling on supplements without an apparent deficiency doesn’t just waste money – it can actually harm your hair. Some nutrients, when taken in excess, have been linked to hair shedding and thinning.
Too much of these can trigger hair loss: 1,2,3,4,5
- Selenium – Often found in “hair growth” blends, high doses have been associated with telogen effluvium and brittle hair strands
- Vitamin A – Excessive amounts can speed up hair’s natural shedding phase
- Vitamin E – Overdoing it can interfere with other nutrients and disrupt the hair cycle
The problem? Many popular hair supplements on the market contain mega-doses of these nutrients, and sometimes several times above your daily needs.
