It cannot change your hair type it just softens or slightly loosens the hair texture growing out from your scalp, the main reason people take is is to reduce shedding, strengthen and grow hair faster, results are different for everyone, some people have had the opposite side effect and the hair becomes coarser. It really does depend on the how long you take it for, the amount and brand. i take 10,000mg Lignisual MSM one of the highest quality and i have noticed that my hair is growing in softer and isn't as coily its just a side effect of MSM, not everyone has this effect.
