what is in henna that reacts to hair dyes, do any hair dyes not react with henna?

Answer 1

Henna Coats The Outside Of The Hair And This Coating Makes The Hair Resistant To Any Other Chemical Process. But, Because The Coating May Not Be Even, Other Chemicals May Affect Only Parts Of The Hair. Making It "Blotchy" Or "Streaky" Also Some Hennas Contain METALLIC SALTS To Give It A "Color Tone" (Ash/Brown) As Natural Henna Usually Produces Some Form Of Red Or Red-Orange And Metallic Salts React VERY BADLY With Other Chemical Processes Sometimes By Destroying The Hair And Burning The Scalp.

Answer 2

I've in no way spotted any difference from common swimming in swimming pools. Skin henna certain, swimming pools spoil it, however it is extra the soaking in water than the chlorine that is the drawback. Your colour cannot particularly difference in any respect in your hair. If a unusual response happened from hair dyes, in just about each and every case it is while a man-made dye with ammonia or peroxide was once used after a steel dye. Metallic salts react in loopy methods with peroxide or ammonia, turning hair bizarre colours and even worse simply burning it off. Natural plant dyes probably in no way rationale those interactions, considering they don't include steel salts or chemical lighteners. Fifty years in the past, steel dyes had been customarily combined with henna or different vegetation, and advertised as "henna dyes", which actually they real were not. So as a consequence the confusion approximately blameless henna, it is the metals that rationale the obstacle, no longer the henna.

Answer 3

Metallic salts and additive react to your hair if it is in the henna.
If you want to use henna safely with chemicals later on ot not, just make sure you buy henna powder that is called body art quality and this is usually found through online suppliers who keep a high quality stock !!
Hope this helps

I dont know but my hair is colored and relaxed and I use henna and it works for me. I dont use henna to color my hair only to strengthen so I dont know. What I do know is I heard somewhere it said henna shouldn't be used 2 weeks prior or after a chemical hair process.

Answer 5

As far as I know - all hair dyes warn you about dying you're hair if you have henna in it. I'm not sure why...but I guess it isn't safe.
