naturcolorHaircolor Hair Dye - Twinberry Chestnut, 4 Ounce (4C)

I have used Naturcolor for many years and find - after extensive online research - that it is still the most benign haircolor. If you need to c olor your hair, I can only recommend this brand. I have tried a few other brands before and found this brand the most satisfying.

Es justo mi color y agarra bien en el pelo pero hay pocos en vent en este tono.

I like this product in every way. It's easy to apply, no lingering odor, and rich colors

Review for the 6C: This is a very nice, more natural dye. It has the ash tones I am looking for. I used it to help get rid of red highlights from dying with henna. This was using the real henna, not the commercially produced henna mixes that may contain metallic salts. Seems to be working well.UPDATE: the 6C still has alot of red tint in it that shows after a few washings. I no longer use 6C, but instead, use 7C mixed with a small amount of 4C in an attempt to get rid of the reddish tint residue that shows up (even with using a bit of 4C) --- the "C's" in NaturColor are supposed to be ash, not reddish. It does help some to get a more ash tone by mixing the 7C with a small amount of 4C, in an attempt to get a medium ash brown.UPDATED REVIEW, regarding the 7C, as Amazon did not let me review the 7C by itself because the 6C review already existed --- the colors should be reviewed separately as they each have a different set of ingredients and intended effects.7C Review:When I use natural or organic skin and hair care products, I research their ingredients at ewg.org, an online site that evaluates hundreds of ingredients used in hair and skin care products.Many products say that they are "organic," "natural," or "botanical," but often contain a mixture of natural/organic ingredients along with ingredients that are toxic or at least questionable. ----- In NaturColor 7C, which I use myself, there are 3 questionable ingredients, listed at the end of the product's ingredient list, labeled high in toxicity or allergenic, at ewg.org: p phenylenediamine (or PPD) (a #10, high in toxicity or allergenic), p aminophenol (rated a #6), and M Aminophenol (rated a #5); all 3 have a high toxicity/allergenic rating at ewg.org ----- These can be found by entering the term into a search engine field, for example, "ewg.org M Aminophenol" as an easy way to look it up, if desired, and copying and pasting the ingredient name. PPD is primarily used in dark hair dyes, whether natural ones or not.I use this hair dye because it is one of the more natural ones out there, but if I could find one using effective natural alternatives to the PPD and the others mentioned above, I most certainly would.The only other complaint that I have is that the darker NaturColor hair dyes that are supposed to be like some sort of ash brown color, have noticeable tints of red that show up, especially after a few washes. The less "natural" hair dyes also have too much red in the darker brownish tints, and I am sure, in the black ones as well. Is there really no way to get rid of the reddish tint and replace it with a true botanical medium ash brown tint? I have tried the lighter tints and either they are too light or have even more red in them. Although I have tried it, I don't presently use natural henna, even combined with the natural indigo herb to get a brown color, because the indigo is the first to wash out, and leaves you with auburn red hair. I have naturally ash medium brown hair. And it is difficult to get rid of that red henna color, regardless if it is natural.One of the hallmarks of dyed hair, in darker colors, is the reddish tint. People notice that red tint and wonder if you dye your hair. It seems to be almost impossible to get an ash medium brown tint from any hair dye, natural or not. I may experiment with using walnut dye that I create myself.

Tried several brands that contain no amonia or parabens but Naturcolor hair dye is the only brand that I trust. No unpleasant odor. No itchy scalp. Absolutely cover my gray hair areas. Most importantly they use safe ingredients that does not damage your hair & scalp. THANK YOU Amazon for carrying this excellent product!
