Are there any vitamins sold in store that will make my skin, hair and nails healthier?

What Affects The Health Of Your Hair, Nails And Skin?

Brittle nails, weak hair and blemished skin are often signs of vitamin or mineral deficiencies. A healthy and balanced diet, plenty of water and regular exercise can be a good place to start if you’re looking to improve this, but it can take up to six months for you to notice a difference, even with dietary supplements. It’s also important to remember that stress can have a huge impact on the health of your hair, nails, and particularly your skin.

Store-Bought Vitamins

Many companies sell specially-branded vitamins, lotions or serums that claim to improve the health of your hair, skin and nails. It’s important to check the active ingredients before you buy, as these are often just overpriced B-complex vitamins, which you can get much cheaper if you opt for the generic or non-branded version.
