It's like a lotion for your hair

I saw an immense improvement in the overall health and strength of my hair after using this repeatedly every night before bed. I have fine, low porosity hair and this seemed to penetrate and moisturize it very well. The smell is lovely. My only hesitation in repurchasing this product is the price point. With that said, I would recommend for someone who needs that initial boost in repairing/strengthening their hair

Game changer for fine hair with extensions

I have fine color damaged straight, sometimes wavy in the right humidity, hair that has two rows of NBR Extensions. This overnight treatment with another brand‘s hair oil, not naming names here, has really transform my hair. This works really well if you put it on and then put your hair in one of the silky ties as well, especially if your hair is prone to never holding curl. This really improves the quality of your hair in double times as a great styling tool in your sleep. I’ve seen my hair go from weak and breaking too strong and long.

Unruly, not quite curly hair feeling nurished

I recently moved from California to Virgina and the humidity has brought my frizz to life. This helps me tame that and get a smooth look and feel. My hair feels thirsty at the end of a long, hot day and this helps quench that and soften any unruliness.

Ingredient change?

Did the ingredients change? My previous bottle did not say plant proteins. This new bottle is destroying my hair-it’s now super dry and brittle. I’m wondering if it’s too much protein for my hair?!! Super bummed because my previous bottle was perfection even for my fine, thin hair.

Game Changer

[This review was collected as part of a promotion.] I’ve been using this for a couple of months now and it has completely transformed my hair. I had dry hair that was prone to breakage and this helped restore my hair to shiny and healthy. Worth every penny.

Happy Surprise

Hate to say it (because of the price), but I’m a big fan. I have curly hair and put this in at night when my hair is damp or dry. I’m noticing healthier and shinier hair. It smells nice as well.

I hate how much I love this.

I did not want to love this product as much as I do. It’s so expensive. I’ve used ALLLL the brands, premium and drug store. I thought that there is NO WAY this product is going to be so good that it warrants the price. And if it IS THAT GOOD, there has got to be SOMETHING out there a bit cheaper to produce similar results. I searched. There is not. The 8h magic serum is literally magic. It’s keeping my hair silky, soft and frizz free. My hair is medium coarseness, euro, straight to wavy, low porosity roots and mids and high porosity ends. My ends have been coarse, dry and my hair gets frizzy. I can never wear my hair down because it will tangle and frizz so I always claw clip it up. It has baffled me for so long as to why my ends are so damaged when I NEVER use heat tools, maybe twice a year when I’m feeling extra, and I don’t color treat it. I don’t really do anything to damage my hair so why is it so damaged at the ends. I think that’s just the way my hair is. I’ve come to the realization that just because I’m avoiding damaging habits, like heat and color, doesn’t mean I’m doing enough to keep my hair healthy. The leave in products I’ve been using are not doing enough to keep my hair protected and healthy. But this is like a magic potion and my hair is transformed. I’m using it on both my daughters now too and their hair is gorgeous. So soft and silky.

Too Much Parfum

While I do like the serum, it is extremely fragrant. While the end result is okay, it is not worth the price nor suffering through the fragrance.
