    Great product recommended by my stylist. I honestly don't know how I lived without this - oh, wait, I did but my hair was super dry and frizzy. Now my hair looks and feels healthy and shiny.

          After putting a small amount of this in and blowdrying my hair straight (my hair is wavy), my hair is SO soft and smooth. This was recommended to me by a stylist, and he wasn't wrong. Good value with a coupon or $ off, otherwise a little pricy. Still amazing either way though - would buy full price.

            I would buy this again, but recommend it for thicker and heavier hair. I use it when I spray too much hair spray on. It gets out the excess spray without breaking hair. It does make dull hair shine. But for fine hair you just have too use very little.

              Although I purchased it with a new straightener (Sedu), my hair has looked great with minimal styling. My normally frizzy hair has remained calm and healthy looking despite being out in drizzly rain in hot and humid SE Alabama! I have been using it for one week and my hair has transformed from straw looking and feeling to relatively soft and bouncy.

              I purchased this after watching a hair expert on youtube (when will I learn?). This stuff is terrible. It was like I used nothing on my hair. I more than likely will toss this product, unfortunately.

              I recommend Caviar Anti-Aging Replenishing Moisture Milk (Ulta carries this product).

                  A:

                  AG Hair does not claim that the Keratin Repair Repair Serum Keratin Anti-Breakage Sealant has heat protectant properties. We recommend using either AG Hair Colour Care Deflect Fast-Dry Heat Protection (Item #: 2290214) or AG Hair Smooth Firewall Argan Shine & Flat Iron Spray (Item #: 2290234).

              • Q:

                Is it true that you can never use too keratin or can too much keratin mess up hair?

                  A:

                  From AG Hair:

                  KERATIN CHEMISTRY — WHY HAIR BREAKS:

                  There are numerous reasons why hair might break including mechanical (brushing, elastic bands), chemical (colouring, bleaching, hi-lighting, chlorine, salt) and environmental causes (UVA/UVB degradation). These processes harm the outer cuticle of the hair shaft leaving hair dry, brittle and prone to breakage.

                  Since keratin is the primary building block of the hair cuticle, introducing keratin back into the hair is the only way to repair it. Keratin penetrates the hair cuticle and bonds to the brittle, broken scales helping to restore strength and moisture, and prevent further damage.

                  The Keratin Repair category is formulated specifically with an abundant amount of keratin to make your hair visibly stronger, shinier and healthier with each use, and can be used daily as a reparative and preventative treatment. It is not possible to overuse keratin.
