B5, works.. but does it cause hairloss?

[Dreamer99]

I have been taking B5 for a couple of weeks now, and I have noticed my hair has been thinning.. is hairloss a side effect of B5?

I know that B-5 is good for hair in general and is used in many shampoos. I suppose in extreme dosages it can have a negative side-effect.

Using it for over a year now (3g/day), haven't noticed any hairloss (or other side effects) whatsoever.

I was taking 10g a day for about six weeks up until last week when I stopped because I'm now on Roaccutane and there's no need for both. I didn't notice at first (maybe it took a while) but the B5 must have caused my hair to become really dry since recently it looks terrible. I have fairly dry hair naturally but it's usually manageable with some gel or wax. I resorted to clipping it down to grade 2 to reduce the appearance of split-ends but they looked worse with the shorter hair. It's been growing back for 2 weeks now (I can't wait to have my fringe back ) and since stopping the B5 it's looking healthier and stronger every day. I didn't experience hair loss, but definitely a loss in hair strength and integrity. Not even Roaccutane causes that much damage.

Dreamer99, whats your complete B5 regimen?

When taking a high dose B5, you should/must take a B-complex to minimize vitamin deficiency. Vitamin deficiency might cause hairloss. A lot of people somehow don't seem to know this.

Dreamer99, also take extra biotin (vit H/B7/B8 ) because a B-complex usually does not contain much biotin. Biotin is good for the hairs and might improve the effect of B5. A high dose of B5 can cause biotin deficiency which might cause hairloss. Because you are experiencing hairthinning, I would start taking 3mg biotin/day or more. Biotin can be cheap ([url removed]) and does not (as far as I know) have any sideeffects.

I would like to know how you progress, because I have experienced the same while on B5. I don't know if it's caused by B5, because in my case their might also be other causes. So please keep us updated.

@Jhart999,
did you take a B-complex while on B5?
