I've been using henna about every two months for over two years and somehow have never heard about henna build up before. Then I clicked on the "Blogs" button and saw this term in the person's blog that popped up.

I did a google search and the only half-way useful information that I got was here. It says Constant build up of henna from over coating the hair can also cause the hair to become brittle and break. So now I'm concerned.

How much/often is "over coating"?

I have noticed some breakage in the lower 1/2 of my hair but that's also the hair left from when I severely damaged it with and ammonia bleach about 2 1/2 years ago. Could the henna that did such good things for my hair in the beginning be damaging it now?

Please share any information you have about this.

TIA
