L'Oréal Technique Oreor Developer - Hair Color Developer, Creamy Formula For Uniform Results, Combine With Color of Your Choice

good and it works well

Exactly as expected

Good

It has a very good effect when preparing my dyes to make my hair, it makes my color more beautiful.

I've been dying my own hair for years. I do not use box dye. I use the L'Oreal high color for dark hair because I refuse to bleach my hair. This developer works so so well. I've never had any problems with it. No allergies. It's really gentle on my hair. Great value for the price because as we all know going to Sally's can be a little bit expensive. Definitely recommend this

I was bleaching my hair from solid black to gray/silver. From what I read online, this product along with L'Oreal Quick Blue Powder Bleach, were the products to use to start the process (with the blue from the bleach to help reduce brassiness).I chose the 30 developer because 40 would've been too strong and 20 wouldn't have been enough to lighten my black hair. How much you mix of this developer and the bleach depends on how much hair you have. The ratios are printed on the bleach plastic container.— PREP —I washed my hair and didn't put product in it for three days to make sure my hair had natural oils in it before I bleached the first time. I applied the mixture on my hair for about 45 minutes and washed it out. I put some light coconut oil in it for a couple days to help hydrate it (while sleeping with a towel on my pillow).[As an aside, I have heard different things about coconut oil; some people swear by it and some hairdressers say it does nothing. For me, it did help keep my hair from being dry before I bleached a second time.]I then did the bleach process again, and got my hair to about 7/8 on the lightness scale. At this point I thought it was light enough for a gray dye (Joico Intensity Semi-Permanent Hair Color, Titanium, 4 Ounce), and now I have nice dark gray/silver hair and loving it!— SUMMARY —I like this developer and it did the job to turn my black hair significantly lighter. Recommended.

I recommend this product. It works fantastic and is gentle in your skin.

Mixes easily with the color, no obnoxious odor, easy to apply.
