My scalp feels more balanced, and my hair looks fuller and more resilient.✅ Reduces breakage-related hair fall✅ Lightweight, silicone-free formula✅ Easy to apply and absorbs quickly✅ Strengthens and nourishes from the rootIf you’re dealing with weakened or thinning hair, this serum is absolutely worth the investment. It’s a salon-quality treatment you can use at home—and it truly makes a difference. I’ll definitely be repurchasing!

This product change my hair, I had been using this producto for more than 40 days and my hair is stronger now, is shiny and beatiful. Is a little expensive but I tried others products and this is one that I need to keep in my life.

I love this serum, this is my third time repurchasing this item. I have noticed a great significance with my hair health and growth of baby hairs. My hair is also more softer and moisturized. Although it’s pricey I believe it’s worth it. You have to be consistent and patient when using this, keep in mind you sometimes don’t notice till 2-4 weeks after using.

I tell you what...I would use this for the smell alone! It smells AMAZING and has a cool feeling on the scalp. I use it after showering and massaging my scalp. It doesn't make my scalp feel oily or leave a shine, but makes it feel moisturized. A few drops goes a long way but I do feel like I went through the product quickly (this could be user error ha). The serum dropper is easy to use. I love that the bottle and dropper are glass. The product quality feels high end worth the money!

I lost a lot of hair dealing with health issues. It was down to my waist and then I was losing hair and balding everyday. I had to chop it off to my shoulders but that still didn’t stop the hair loss. This did with in two weeks.! I know it’s not technically a hair growth supplement but by not losing hair like I was my hair has grown fast. It’s thick and healthy again. Yes it’s expensive but finding something that actually works was worth it for me. I will continue to buy this. The pictures include how much hair I lost brushing my hair in one morning vs the blue brush how much I lost during a week while using this everyday. The difference is insane.

WELL YES, but I think there are better and more affordable, each hair is different maybe it works better on your hair so if you can buy it do it, the smell is good, something I like is that it can put it with clean hair and does not leave the hair greasy or anything, it is super soft, IF YOU CAN try it!

I’ve struggled with hair loss and extremely slow growth as I have curly hair, I saw this on tiktok and took the risk spending the money. I noticed my baby hairs ACTUALLY growing out along with my whole head. I also saw a big difference of growth within the first month. It’s the only hair oil/serum I’ve tried that doesn’t leave my hair oily and actually makes my hair FEEL better after I use it. I’ve purchased this more than once now.

Definitely made my hair shed less and it smells good.
