Why did you pick this product vs others?: Move over Olaplex!! This bonding oil is fabulous! I love it. I have been a fan of Olaplex but recently tried this, I won't go back to paying the high price for Olaplex anymore.

This product is amazing! It has transformed my hair. Well, truth be told, Cosmolux, and a young hairdresser who shall remain nameless are transforming my tresses. 6 weeks ago they were wheat field dry and I started using this product to its full potential and it as well as the Cake hair line have made my hair thick and LUX! I do take Biotin for hair, skin, nails. I'm older, so products that work are important to me. I can honestly say, my hair looks amazing!!!

This is perfect for your curly hair routine and works like Olaflex, but for half the price. I was on the hunt for a finishing oil for my curl hair routine that was cheaper than the very expensive brand name options and was thrilled with the performance of this one. First, it was not overly scented. I hate using a product and becoming overwhelmed with an artificial scent. This scent was mild and not overpowering. Second, the hair oil was so easily absorbed by my hair. Unlike other products, it didn't weight my hair down, make it look overly greasy or smear all over my sheets and clothing. Third, it easily removed my hair cast without causing frizz!! My hair was so shiny, moisturized, and voluminous after I put this in. Tip-make sure you hair is completely dry before using. This is now an essential step in my hair routine. I add it in right after defusing as the final step. Its the best value for money hair oil I have tried and I have tried around 8 already.

Has a very light pleasant scent. It’s a small bottle but you only need a couple of drops. Works well as a heat protector on color treated hair.

Update: The manufacturer, very nicely, refunded my money due to the bad packaging. Oil is nice, good scent. BUT bottle is terrible, cracked as soon as I opened it, fell apart shortly after.

I'm in Love!! I was skeptical at first but gave it a try and so thankful I did! I've been doing bleach baths every few weeks and using this after Olaplex No.5 and my hair looks as shiny and healthy as it did when it was virgin. And it's strong! I believe in strong part to this product. When I used only the Olaplex No.5, it was soft and strong after a bleach bath but not AS strong and definitely not as shiny. It looks like Barbie Doll hair. They've made a lifelong customer here.
