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

This is the only developer I use along with the powder to match it mixes well does the job efficiently. However I do recommend wearing a mask it is very strong and probably not good to use without opening a window or wearing a face cover!

Great product I used it with my hicolor and it came out good for my first time trying to dye my hair without bleach!

He usado el revelador L’Oréal Oreor varias veces para teñirme el cabello en casa y siempre me ha dado excelentes resultados. Se mezcla muy bien con el tinte y tiene una textura cremosa que facilita la aplicación, sin gotear ni resecar demasiado el cabello.El color queda parejo y vibrante, y no he tenido irritaciones ni molestias. Me parece un producto confiable, ideal tanto para uso profesional como casero si ya tienes algo de experiencia.Muy buena relación calidad-precio, y el envase rinde bastante. Sin duda seguiré comprándolo para mis coloraciones.

me encanta esta marca de agua para el cabello muy profesional y me gusto que rapido me llego el envio de esta agua oxigenada amo la estuve usando por 3 years y muy buena la recomiendo 100%

I've used this to lighten my brows with baking soda and it works fine (although it's not their intended purpose).

Buen producto

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 used this with L'Oreal Quick Blue Powder Bleach. It did a good job lightening my hair, I think any dark spots were more of an operator error than anything. It takes practice to do it right, especially if you have a lot of hair. I was able to go from a medium-dark brown (3 or 4) to about a medium-light blonde (7 or 8) in about an hour. I also bought the 20 volume developer for toning and future root applications because I trust this brand.People are shocked when I tell them how little you have to spend to bleach your own hair. For around $25 bucks, you can buy yourself Developer, Powder, a Brush and Bowl set, and some rubber gloves (you NEED gloves, trust me!). That will buy you enough bleach applications to last you indefinitely. You may also want to invest in some professional foils, but I've used regular aluminum foil with success.Learning to bleach your own hair is definitely worth it, but there is a learning curve. Make sure to bleach the ends first and leave your roots for last, or there will be a noticeable disparity in color from root to ends! Also, don't try to apply bleach to huge sections of your hair, or you risk missing some spots on the inside of each large section. Instead, take your time and apply to smaller sections so that you can apply the bleach evenly.
