I just love the whole olaplex line 💜 The only thing I don't feel I can use is the oil, it's quite deep and golden in color and it transferred onto my newly bleached hair. That's the only negative thing I can say, but if you mix it in with conditioner or hair mask, it should be fine. The purple shampoo is also very strong in color, so I mix it into the shampoo, I don't feel the purple is as nourishing as the regular one, the hair gets a bit drier. Other than that, everything else is just positive 💜 What I do is wash my hair 1 to 2 times a week, you shouldn't wash your hair too much, and if you're like me where there's often bleaching in the regrowth and otherwise someone who colors their hair, I use colour bomb color that doesn't damage the hair but gives a nice purple tone, this shampoo is also nice to use. My routine is to first spray my hair with that bottle, and when it has worked a bit, I take number 8 as a treatment. I wash with shampoo and then hair mask number 3, followed by conditioner. Then I put in oil, I use biosilk and number 6 which is actually a leave-in styling product, but it's excellent for protecting and shaping the hair when you blow-dry, and then it stays absolutely gorgeous 🥰
