Deep Conditioning Boost That Leaves Hair Softer
Scent: Keratin
I’ve been using the Keratin Hair Mask as a weekly treatment, and it has noticeably improved the overall feel and look of my hair. The mask has a rich, creamy texture that’s easy to apply and spreads smoothly through damp hair.
After leaving it on for the recommended time and rinsing, my hair felt softer and looked more hydrated. It helped reduce tangles and left my strands feeling smoother compared with regular conditioner alone. On days when I skipped styling products, my hair still looked healthier and less frizzy than before using the mask.
The scent is pleasant and not overpowering, and the mask rinses cleanly without any heavy residue. Over time, I noticed less dryness and a bit more shine, especially toward the ends where my hair tends to feel drier.
Pros:
Deep conditioning that improves softness
Helps reduce tangles and frizz
Pleasant, not overpowering scent
Rinses clean without residue
Cons:
Not a dramatic repair for severely damaged hair
Can feel heavy if left on too long
Overall:
This keratin hair mask is a solid choice if you’re looking for extra hydration and smoother texture between washes. It provides noticeable conditioning without weighing hair down and works well as part of a weekly hair care routine.

It keeps my hair looking great curly or straight
Scent: Keratin
I love this hair mask or conditioner. Not sure what it’s called. I know that I tried it a few years years ago and it really worked great with my thick curly hair. And it looks great when I blow dry it in my hair looks amazing shiny. I really like the product. I usually buy it every month, but I had suffered for a few months nothing wrong with the product. I just like to try all types of products I put in my hair whenever is out there new or old I will try it like I said my hair curly not very curly but enough that I need strong, thick conditioner I don’t like the I usually say my hair is damaged and that way I get the thick shampoo and conditioners thank you.

Best Stuff Non Greasy Super Shine
Scent: Argan Oil
Wow! This product blew my mind! I have fine hair, bleached blond and this product made my hair soooo shiny nothing has ever done that! The fragrance is minimal but pleasant. This improved the condition of my hair immediately and I didn't even leave it on very long. No greasy feel afterward which is important with my fine hair. I bought another for daughter's frizzy hair she was impressed.
