I like to dye my hair a light ash brown/blonde, but it always fades to a brassy color. I hated re-dyeing my hair because that meant I was constantly applying chemicals to my scalp, which always led to a headache that lasted the entire day. So I decided to search online and came across this one. I didn't know whether to choose one of the ash blondes or the other colors, so I found some color swatches online and decided to choose the wheat blonde since that was the ashiest of all of them. I tried it out as soon as I received it and I did a strand test to see if it would give the color I was looking for and then applied it fully to my hair and left it on for 40 minutes. After washing it out and blow drying, my hair looked great and was the exact shade of ash brown/blonde I wanted. My hair was also shinier and looked healthier. I have a little below shoulder length hair and I didn't even have to use the entire package. I still have enough for another application. The instructions were simple and it comes with gloves, an application brush and a plastic cap. It is truly organic and it makes me feel awesome that I'm not using a product with chemicals like PPD, ammonia, parabens, etc. It is pricier than regular boxed drugstore dyes, but overall, I absolutely love this hair color and will continue to use it. I highly recommend! :)I used the dark brown color after suffering from allergic reactions to the permanent and semi-permanent hair commercial products. I am now done with chemical products after many years of use and am glad to have found a natural dye solution for my gray hair. Because it is a natural product, I have to be content with the fact that it does not work in the same time frame or conditions as a chemical product.It is a dry powder and you need to mix it with hot (not boiling) water. My hair is shoulder length so I can get 3 applications out of a 22 oz box.First: You MUST wash your hair and NOT apply conditioner. A hard habit to break. This product needs to absorb into your hair shaft.Time:It seemed to work best when I left it on for 90 minutes and used the hair dryer for heat at least 3 times with 20 minute intervals between.Smell: It smells "green" like plants. I don't know any other way to describe it. But to me it is better than the toxic chemical smells of other hair products.Effectiveness: Acceptable coverage of gray hair but not as thorough as a chemical product. It will be different for each individual.Hair Condition: My scalp is now healed of the rash, itching, and blisters, as well as the dry hair I was suffering from with the chemical hair color product. My hair was soft, and shiny after use of the Radico.Final Evaluation: I am willing to deal with the change in process between a natural product like Radico and chemical hair color products because I am no longer exposing my system to cancer causing products. Fortunately, my scalp and hair agree with my choice.I love this product and have been using it for about a year now. I tried the strawberry blond and the auburn red first before liking the light brown best. The strawberry blond and auburn red left my hair a bit too bright for my taste. I've found the light brown has a slight reddish color which is all I"m looking for. I feel this product works best on hair that has not been dyed with chemicals. When I first started using it half my hair had been dyed blonde with chemicals and the dye didn't take very well until after several applications; however, the part of my hair that had grown out and was not previously dyed worked great with the organic hair color on the first take. Don't leave it on much longer than the directions say especially if you're using one of the reddish dyes; there's a good chance it will look like a clown. As for the smell, if you are used to scents and fragrances of conventional beauty care products this might smell weird to you. I don't mind the smell personally. It sure beats the eye-stinging smell of chemical hair dyes that warn you to have good ventilation when you use them! When you mix the dye the color is green, but I promise that my hair has come out looking the color on the box every time.Overall I love this product. It gives my hair a great color and leaves it shiny and soft. If you are looking to change to natural/organic beauty products you've found the hair dye you've been looking for.Why would anyone use chemicals to dye their hair? peroxide eats hair. These are plants and coat hair. My hair is as shiny as it was when I was a kid now that I have stopped chemically treating my hair for a year. This light ash blond coats my grays enough so that it looks as though I spend a fortune highlighting my brown hair. My hair is a gorgeous shimmering light brown with this product. if your hair is prone to brassy undertones than you must have indigo on hand. You can mix some into the dye or apply later if an issue. I always add a bit of indigo to my hair.if your hair is frosted than be very careful with indigo. This product came quickly and is less brassier than most- they use a colorless henna to help dye, which is a smart technique. Strand test can be done by collecting hair from your brush if you don't want to cut snips of your hair. I love Radico Colour Me Organic products, The Henna Guys, and Colora henna products... Also, if you are trying to let your hair turn gray gradually- this is the way to go. Just do less time each time and eventually you end up with gray hair. WE all know that colored hair on old leathery faces just looks awful.I will never use chemicals in my hair again and Radico is so perfect with its all natural ingredients! The color is gorgeous, my hair is so healthy and growing back nicely after being fried off with bleach! I have colored my hair for 30 years and never used such a great product. No more dry hair, split ends or damage from chemicals!! My hair is so soft and looks healthy and shiny! I LOVE Radico natural color!I've been using this brand to dye my hair for the past 3 years. I've used brown and find that the colour had too much of a red hue for my liking. I mix brown with dark brown. I need to leave the colour in longer than 1 hour (2-4 hours) but it actually works! I would say I'm about 70% grey. 5 stars even though I have to leave the dye in longer because I've tried other henna-based natural products that didn't work.This product damage my scalps. The supplier is ignoring my messages.Mes cheveux sont vert!! Aucun violet la dedans et j'ai appliqué sur cheveux naturels brun foncé!This color is very nice. By applying it, there is shine in the hair and the natural color comes very well.It didn’t cover a single white hair! What a disappointment! What a waste of time and money!
