VITAMINS hair cosmetics Keratin Hair Serum with Biotin, Castor Oil & Collagen - Anti-Frizz Heat Protectant & Leave-In Shine Treatment for Dry, Damaged, Color-Treated Hair - 4.25 fl oz (125mL)

BEST HAIR PRODUCT OF MY LIFE!!!! I’ve purchased hundreds, if not thousands of hair products over multiple decades of my life. Suffice it to say I have a veritable arsenal of hair products. There are many products in my arsenal that offer very good results for what I’m looking for in a hair product, but this product goes way above and beyond, offering OUTSTSTANDING results. It didn’t just soften my hair, as many products do, my hair feels brand new, like it did seven decades ago when I was a completely natural blonde. Beyond the softness and sheen it gave my hair, it also tripled the volume of my hair just because it made all the damaged hair healthy again. I’ll be a lifetime consumer of this product. PLEASE don’t discontinue it!

This product smells great!! I can already see a difference in shine and softness. When I apply it I feel like my hair instantly feels stronger and more elastic.

I love this product. I am 68 y.o. and only wash my hair once a week as it is dry. My hair is thick and coarse but I still color it so I need some help with moisture. This item FITS the bill. I apply about a dime sized amount in my hands and rub it through my strands concentrating on the middle and ends while my hair is a little damp. It has helped tremendously and leaves my hair looking and feeling moisturized. I've ordered this a few times and will continue.

It smells wonderful & your hair will have a soft silky feel…

Great product, I use it after I wash my hair. Helps with hair growth and my curls look beautiful.

The best way to put it is I wash my hair everyday because I work in manufacturing, so it gets really humid and hot and I’m around a lot of chemicals, materials that have a type of dust in them, this product I use on the mids and ends, I’ve noticed my hair isn’t as frizzy or looks dehydrated and broken, it’s much softer. The downside of the size of the bottle, I wish it was a little bigger.

I use the 3 days a week at least. My girls use this. It helps our hair not look so dead on the ends and helps with frizz control. We all have long normal hair type. The ends just sometimes look dry and this is the perfect fix tomorrow make it look a feel healthy. Also last a while cause a little goes a long way.

I have very thick hair and it was getting dry as I age. It was also looking frizzy. I have been using this and my hair is so much softer. Although it doesn’t make the phrase go away completely, it definitely tames it. Would buy again.

Ottimo prodotto, lo utilizziamo tutti in famiglia! Lascia i capelli nutriti e a lungo andare si nota che il prodotto ha effetto sulla salute dei capelli! Ho acquistato anche lo shampoo, non ha bisogno di balsamo, ottima linea alla keratina!

I am a return customer for this product, its very good on my thick unruly hair, does exactly as it says on product description 😊
