## Description

desertcart.com: VITAMINS hair cosmetics Keratin Hair Serum Oil for Frizzy, Dry, Damaged Hair - Anti-Frizz Shine Gloss Treatment, Heat Protectant with Biotin, Castor Oil and Collagen - 4.25 fl oz : Beauty & Personal Care

Review: Lo mejor para mi cabello Smooth, Shiny, and Healthier Hair – My Go-To Keratin Serum - I’ve been genuinely impressed with this Keratin Serum. The formula feels lightweight and absorbs quickly without leaving my hair greasy or heavy, which is a huge plus. After using it consistently, my hair looks noticeably smoother, shinier, and much more manageable. It really helps tame frizz while adding softness and a healthy-looking finish. I also appreciate the ingredient blend — keratin, biotin, castor oil, and collagen — which makes it feel like a nourishing treatment rather than just a styling product. Another big benefit is that it’s alcohol-free, sulfate-free, and paraben-free, making it gentle enough for regular use. If you struggle with dry, dull, or damaged hair, this serum is definitely worth trying
Review: Love the Scent - This is 3rd time purchase. Love the scent. Give a nice clean smell to hair. It leaves hair smooth. Does not feel greasy. Everyone comment how my hair smells good, when they give me a hug.

## Questions & Answers

**Q: Does this product have Formaldehyde and sulfate?**
A: No,this unique Keratin Hair Serum doesm't contain Formaldehyde or Sulfate

**Q: Is this product safe for keratin treated hair ?**
A: I use this product once a week and I cant image it not being safe.  I have never had the keratin treatment at a hair salon, but I use a leave in conditioner, heat treatment and infusion therapy keratin replenisher daily on my color treated hair and I have no issues.  Plus the keratin protein weekly on top of all the other products with no issues.

**Q: Is is this product most effective when applied to dry or wet hair?   many thanks.**
A: I think the conditioner is meant for wet hair and this is to apply to dry hair after it's been fixed or blow dried. After I'm done blow drying it, I apply it and it gives it a nice shine. But I'm sure it'll have the same effect if applied to wet hair and then have it blow dried.

**Q: You add this to wet hair ? Is this a heat protectant?**
A: Yes, you add our unique Keratin Hair Serum on damp hair.
Please see the Directions section: "Apply a few drops to your palms and spread thoroughly on dry to damp hair from hair root to tips."
It Is a heat protector, although you will see it evaporates as it is water based.

### ⭐⭐⭐⭐⭐ EXCELLENT FOR DRY, CURLY HAIR!
*by T***7 on September 6, 2025*

THE ABSOLUTE BEST FOR DRY, CURLY HAIR! ✨️ I am 60 years old and have very dry, wavy, curly hair. I use TreLuxe leave in products, then diffuser to dry. Before my hair is completely dry, I use a few pumps of this, rub my hands together, and scrunch it into my hair, then diffuse a little more. (Don't dry completely.) After about an hour or so, it is usually dry, depending on humidity, and my hair is super soft, no frizz, and shiny! I don't have to wash it again for 3-4 days! Just use a spray bottle with water each day, between shampoos, and it looks amazing! I have used this product for several years! It's a game changer for dry hair!! 💖
