Possible explanation for dry post-henna hairPosted by Rainbow-Vanessa on February 9, 2005 at 00:24:37: I was looking for a 100% natural shampoo when I came across this onone company's website: "Most likely, your current shampoo, conditioner or styling products contain some type of polymer, a PVP petrochemical, carbomer or hydrolyzed synthetic protein (soy, wheat, oat) which adds a coating to hair to make damaged hair appear undamaged. Certain hairsprays also use these gums and polymers. Some of them are very hard, thus making it difficult to remove them with [their product - a clay-based cleanser]. It usually takes several washings to completely remove these "gummy", "oily" residues from everyone's hair." "...The chemicals used to change the hair [into colored, highlighted, permed or straightened hair] alter the outer layer of the hair shaft creating a porous cuticle. The more porous the hair, the more the hair will absorb these polymers and gums. With some people, before these gums are completely removed from the hair [by the natural shampoo], there may be a "stiff," "sticky" or "dry feeling." Be patient! After a few more washes you will be free from these synthetic residues. Very frizzy or kinky hair is particularly porous and absorbs a high percentage of these polymers also." Well, I know henna is not a shampoo, but if it does somehow get rid of the first layer of chemical coating, exposing the residue, maybe this is why it feels so dry for some people. You don't need to have had your hair chemically treated to have porous hair. I've noticed often the people complaining of this dry hair feeling have commented that the colour took very well, which I imagine (correct me if I'm wrong)would be the case in more porous hair. Just a theory...
