KERASILK Liquid Cuticle Filler | Heat-Activated | Provides Long Lasting Hair Cuticle Protection | Rebuilds & Optimizes Hair Surface | With Heat Protection | For Stronger & Smoother Hair | 125ml

I bought this product based on the fact that it was recommended in a New York Times Wirecutter article., and I'm so happy i did. My baby-fine hair tends to frizz and have multiple fly-aways and get very static-y. This product has helped greatly with all those issues. I will definitely be buying it again.

This seems to tame the frizziness that happens with hair dye. It only take a small amount so the bottle should last a long time.

This helps the your hair keep its color longer and makes it feel healthy and fresh. Its scent isn't overwhelming. It works well with the Repairing Spray

It works so well that I do not have fly away hairs after I take my wool hat off.

Great smell and great detangler

One of my favorite heat protectants to use for my hair. I have thick curly hair and often use a flat iron to style my hair. This is one heat protectant that not only keeps my hair smelling good but also looks good. I don't have to walk around smelling like I cooked my hair and my strands continue to look lovely. No nasty chemical scents! There are so many ingredients in this heat protectant to provide nourishment to the hair, unlike a lot of protectants. My hair maintains a silky, frizz-free appearance after I take my iron to it. I have noticed little to no breakage when styling my hair. The hair also doesn't feel greasy or like it is laying down flat. It has so much life to it and love. I highly recommend this heat protectant to not only those with already straight hair but us curly girls that need the extra loving!

It has so much alcohol in it that it stripped my toner. My hair is more frizzy and dry than normal. I only used shampoo and this product.

This is a good product. It really is nice.Easy to spray on towel dried hair before blow drying or ironing.Has a slight but pleasant scent.Not drying to my processed hair. It does have alcohol in it as others noted but my hair specialty product by Jack Winn heat protector also has it. So that is not a worry just a necessary ingredient.It did not weigh my hair down at all.Nice shine.I deducted a point. Because there are no instructions on the bottle or indicators on label of its intended use or uses. The label has information behind it but no instructions or useful info. I do get annoyed when I have to go to ad to find out just basic info on product. Definitely not a gift item to put in basket for a college student or such. They did a good job of showing in ad all the good ingredients. But only one small sentence saying to spray on towel dried hair. And another spot indicates heat protector. Since most products called cuticle fillers are for nail care I think they should give more useful information on this bottle. They also run the risk of losing repeat or new buyers if the consumers are not researching and using it correctly. It should simply be on the bottle or box.
