3 reasons apple cider vinegar may be good for hair

HySpin says…I have started incorporated Apple Cider Vinegar (ACV) rinses in my hair care practices with great results. My hair is very, very kinky and I find if I do the apple cider vinegar rinse as the final cleaning step of washing my hair I find my hair feels smoother, reflects light more (shinier) and it is easier to detangle. But what is the apple cider vinegar really doing to my hair?

The Beauty Brains respond

In actual lab testing we’ve haven’t been able to demonstrate much of an effect from vinegar. But since vinegar is an acid, in theory, there are three things that the low pH could be doing for your hair.

Three Ways That Apple Cider Vinegar May Help Hair

1. Tightening the cuticle.
If your hair is damaged and the cuticles are upraised, an acid rinse could be helping them to lay flatter and therefore improving shine and detangle-ability.

2. Boosting conditioner efficacy
Conditioners based on quaternary ammonium compounds work better at a lower pH because the stick to hair better. Maybe the vinegar is helping to “lock” your conditioner onto the hair.

3. Removing shampoo residue
If shampoo isn’t rinsed completely it can leave a dulling residue on hair. Vinegar may be helping to remove buildup and letting the natural hair shine through.

The Beauty Brains bottom line

Again, these are only theories. We have no prove that ACV is really good for your hair. The general scientific consensus is that conditioner will do a much better job than any kind of vinegar rinse.

    I use a ACV rinse and it seems to make my hair a little easier to comb after washing- I assume from the laying the cuticle down effect. Mainly, though, I use it because our well water has LOTS of magnesium in it that I’m trying to get out of my hair.

    I live in an area with extremely hard water. I find that rinsing with ACV helps my hair be more manageable and I experience less product buildup.

    ACV contains very essential nutrients such as potassium which are required for hair growth. It helps to repair split end of your hair and make hair soft. Apple cider vinegar has PH value of 4 , hence it helps to restore natural PH balance of your hair.

      Hi Jessi. I’m just curious if you’ve ever seen any evidence that nutrients from ACV (like potassium) do anything for hair growth when applied topically. I can’t find anything in the scientific literature that supports this and if you can tell me your source I’d really appreciate it. Thanks.

    Hello, ACV is often indicated to treat scalp problems, is there any evidence? Thanks.
