FAQ:

Q: Does biotin really work for hair loss prevention?

A: While biotin is added to some shampoos that claim to reduce hair loss, there is no evidence that this works. Consuming foods rich in healthy vitamins and minerals will help with overall hair health. The best natural sources of biotin are meat, eggs, fish, seeds, nuts, and vegetables.

Q: Does biotin make your hair grow longer?

A: Yes, biotin, or B-complex vitamin, proves effective in helping your hair grow longer and faster. It is possible to find biotin in both food and supplement form. Any deficiency of this vitamin will make your hair fall, which is mainly because biotin is important for cell proliferation.

Q: Should I take biotin?

A: if you have kidney disease; if you have had stomach surgery; or if you smoke.

Q: How long does a keratin treatment last?

A: Formaldehyde. Many (but not all) keratin treatments contain formaldehyde,which can be dangerous if inhaled. Formaldehyde is what actually makes the hair look straighter. Cost. Each treatment can range anywhere from$300–$800,plus tip. … Hard to maintain. Washing your hair less and avoiding swimming might make it harder to maintain for some people. …
