Vinegar and hairPosted by Fia on January 26, 2004 at 06:23:15: In reply to: Re: Vinegar rinse to prepare hair for henna posted by kavi on January 25, 2004 at 23:01:11: : Would vinegar have a negative effect on the hair?No. Vinegar is slightly acidic - so is the natural mantle on hair and skin. When washing you're turning the environment slightly more alkaline, which will open the cuticle on the hair. Open cuticles makes the hair more receptive for conditioning and/ or color depositing (hence the use of ammonia in regular hair color - it's highly alkaline and will push the cuticle wide-open), but also more vulnerable as hairs will catch on eachother and loose moisture more easily. Rinsing with vinegar (or lemon juice) diluted in water will restore the acid mantle of hair/skin and close the cuticle. Hair will feel smoother and will look shinier as a closed cuticle layer reflects light better. I find that a final rinse with diluted vinegar _after_ henna helps lock in the color. /Fia
