Everyone wants to look younger, and as a result gray hair remedies abound. Hair coloring is probably to most popular simply because it’s easy to use (but messy), and fast. However, it obviously doesn’t offer any kind of long term benefit or preventative measure. And in the worst case scenario dye ends up looking unnatural.
Next in line would be topical scalp treatments like serums or shampoos that “deliver nutrients to the hair follicle”.

A phytosterol, ²-sitosterol reduces blood levels of cholesterol. Its close chemical resemblance to cholesterol enables it to block the absorption of cholesterol by competitive inhibition. Although beta-sitosterol is not well absorbed by the body (5-10%) when consumed with cholesterol it effectively blocks cholesterol’s absorption, resulting in lower serum cholesterol levels. Beta-sitosterol has also been shown to improve lipoprotein (HDL, LDL) profiles.
PABA (para-aminobenzoic acid)
A form of folic acid, PABA’s primary benefit is improving how protein is broken down and used in the body. Since protein plays such a key role in healthy hair growth, PABA has recently been counted as a vital hair nutrient.
Niacin (Vitamin B3)
