After just a few uses, I noticed my hair felt noticeably softer, smoother, and more manageable. It provides deep conditioning without leaving my hair feeling heavy or greasy, which can be difficult to find in a repair treatment. The keratin-infused formula does an excellent job of helping dry, damaged, or overprocessed hair look healthier and more nourished. My hair feels stronger, has less frizz, and has a shinier, more polished appearance after each treatment. It also helps with detangling, making styling much easier. I appreciate that a little product goes a long way, so the container lasts longer than expected. The consistency is rich and creamy, allowing it to coat the hair evenly, and it rinses out easily without leaving residue behind. The overall quality is impressive, especially considering the value for money. It delivers salon-like results at home and leaves hair feeling refreshed and revitalized. The pleasant scent is an added bonus, making the treatment feel like a relaxing self-care experience. Overall, this is an effective, high-quality deep conditioner that provides excellent moisture, softness, and repair. I would highly recommend it to anyone looking to improve the health and appearance of their hair while adding strength and shine. Review: A win for me - I have been dyeing my hair for over 20 years (and I'm not even that old!!!) so, as you can imagine, my hair has seen a lot and has some damage. I only wash my hair once a week to keep it nice and healthy as possible. I'm in the process of going blond again (hey, if you're gray like I am at a young age, then you can have as much fun as you want dyeing your hair all sorts of colors!). My hair stylist wanted me to moisturize as much as possible in between our very long process of gradually getting me to blond. I decided a mask was in order and after some research, found this. I've done it now four times, and am impressed at how far it goes in your hair - my hair is medium length and thick - and the last visit I had with my stylist, she was impressed with how easily my hair combed out - she says it's always so tangled after she washes out my color - and it feels so soft to me after I use it. I don't love the smell, but as always, I feel like that's such and individual personal preference. It certainly won't stop me from buying again. ## Features - Ultimate Hair Transformation: Experience a total hair makeover with our protein hair treatment, designed to revive and rejuvenate damaged strands for a stunning, healthy look - Deep Repair Powerhouse: Our keratin hair mask for damaged hair dives deep to repair and strengthen, leaving your hair feeling incredibly soft, smooth, and full of life - Hydration & Growth Boost: Infused with biotin & castor oil, this deep conditioning hair mask promotes hair growth and provides intense hydration, making it perfect for dry damaged hair and growth - Frizz-Free Perfection: Tame unruly frizz with our hair mask for frizzy hair, delivering long-lasting moisture and a silky-smooth finish that's sure to turn heads - Salon-Quality Damaged Hair Treatment: Get professional results at home with our deep conditioner for dry damaged hair, a luxurious keratin mask that restores shine, vitality, and manageability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014FVQSAA | | Active Ingredients | biotin, rosemary oil, argan oil, coconut oil, castor oil, keratin, collagen, lactic_acid, vitamin_e | | Additional Features | Moisturizing, Natural Ingredients, Not Tested On Animals, Nourishing | | Age Range (Description) | adult, teen, woman, man | | Age Range Description | adult, teen, woman, man | | Best Sellers Rank | #15,964 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #88 in Hair Treatment Masks | | Brand | VITAMINS hair cosmetics | | Brand Name | VITAMINS hair cosmetics | | Customer Reviews | 4.4 out of 5 stars 18,387 Reviews | | Global Trade Identification Number | 07290015886499 | | Hair Conditioner Type | Deep Hair Conditioner | | Hair Type | Thin, Dry, Curly, Wavy, Straight, Damaged, Color Treated, Chemically-treated, All, Normal, Fine | | Item Dimensions | 3.6 x 2.4 x 3.6 inches | | Item Form | Cream | | Item Weight | 8.8 ounces | | Liquid Volume | 236.58 ml | | Manufacturer | H.Y.

Am I missing something?** A: When stated "Alcohol Free" it means without Ethyl Alcohol (Ethanol or Grain Alcohol). All other are Fatty Alcohol derivatives that are not harmful and good for the hair and skin. **Q: Will this make my hair leas curly and more straight? I’m a dude with curly hair** A: I do have curly hair. This product doesn't make it less curly - just less frizzy. I haven't found a product or method yet that will make it less curly without causing some pretty devastating damage. With that experience, I have decided to embrace the curls and fight the frizz. This product is perfect for that! **Q: Can I use this right after a keratin straightening treatment?** A: Dear Dee, Thank you for your interest in our Keratin Hair Mask. The Mask can be used right after a keratin treatment.
