Great product & it does exactly as advertised
My go to product for heat protection, easy comb thru, detangling, softness & shine. You can use it after a wash & condition , before or after blow drying, & before heat services such as flat iron. It has a nice fragrance , a lightweight feel, & does not feel oily afterwards. You will see & feel a difference in the softness, shine, & body of the hair with the first use. It’s a great product to help maintain & retain hair growth. It even softens the skin on your hands. I love this product & it’s a good value for the price. I highly recommend it.

Effective and Safer
This keratin product is excellent in quality. My first time using keratin treatment and I am glad that this was my choice. After washing my hair I applied the keratin treatment and blow dried my hair then I used the ceramic iron. The results were straight, smooth, and shiny hair. I will definitely use this keratin treatment in the future. It’s just as effective and certainly safer than relaxing.

Worth the money!
I think this was a great purchase for the price! I don’t feel like it really has much of a scent. My hair is noticeably softer though and it does manage the frizz pretty decently. I’ve used it on both wet and dry hair. Very easy to use!There are definitely better products out there, but this one’s pretty great for the price!

I started using this biotin hair thickening serum about six weeks ago. The natural botanical oil blend gives it a lightweight feel—my scalp doesn’t get greasy. After washes, my hair already looks fuller, especially around the crown, and feels stronger (less breakage). I also like that it adds a subtle shine without weighing my hair down. The scent is mild, almost earthy, not overwhelming.

Keratin serum that leaves hair soft and strong
I loved this product, it leaves the hair shinier and more manageable. It absorbs quickly without leaving it greasy. Perfect to repair damaged ends and give more strength to the hair.

Still Static Hair
This kind of works. Yes, it makes my hair shinbut any oil will do that. Ut is a light oil, not heavy or sticky. Is doesn’t help much with static. I still have to trade my hair and the ends are still sticking up from static. I still use it but I’m going to make some changes.It smells like sewing machine oil. It needs something in it to smell better.

FANTASTIC PRODUCT for split ends and damaged hair!!!!!
I really like this product. I have very thin, straw-like hair and use this every time I get out of the shower. It doesn’t leave my hair oily which is a huge plus, but does leave it soft and helps smooth over my split ends. My hair has had a lot of damage over the years due to flat iron usage so this really is a game changer for me. It doesn’t leave a weird smell, I love how soft my hair feels, and it looks and feels so much healthier! I have found that it works really well with just few pumps of it in my hand massaged into my damp hair after a shower. Highly recommend and the price is great for what you get!

Worst product, while using this product I lost the hair line. I’m deeply saddened by adverse effect on scalp.
Amazon Customer –
It’s been a few weeks of usage. Initially I noticed an immediate difference in hair loss, but now I’m not super sure anymore, however I certainly notice more hair growth and my hair has more volume overall! I do enjoy using it for some scalp and my dandruff has significantly reduced too! If you’re going to use it before bed, make sure to have some clothing or towel on your pillow or your pillow might absorb the oil like mine did.
