    this is an AMAZING hair cream.. I'm not a huge fan of having to put the product in my hands and lathering on the hair, i do like sprays a lot more, but this wasn't a heavy product at all. it made my hair truly soft. it also helped detangle my strands for easy brushing! this product also smells good and isn't overwhelming.

          I love this product for my daughter's super dry, curly, hard to grow/manage hair. It instantly softens it and relaxes the curl. I also use it on my straight, thin, color treated hair and it makes it more manageable and shiny. It makes any hair type look and feel so healthy. We will definitely be repurchasing this product when we run out.

              Comments about AG Hair Keratin Repair Repair Serum Keratin Anti-Breakage Sealant:

              I have extremely dry brittle hair that is always breaking off. I have tried so many products, and grabbed this product by accident one day in Ulta. - I thought this was a shine spray. I decided to try it since I was also trying the AG shampoo, conditioner and mask. I am so glad I did! With the very first use, it reduced the frizzy ends and smoothed my hair. Over the next few days, I noticed less breakage! An added bonus was how incredibly soft and touchable my hair was! For the first time in sooo long, it did not feel like straw! I love, love, love this product, and the AG line......definitely recommend it!

                        Keratin Repair Serum is a lightweight formulation that is effective to use on thin to fine hair. For the best result, apply evenly through damp hair. Blow or air dry for a soft, healthy finish. If you prefer, the serum can be applied to hair ends only to strengthen and repair.

                        You can definitely cocktail Keratin Repair Serum with Fast Food Leave On, which will increase both moisture and protein in the hair.

                        We suggest BB Cream as not only does it condition and strengthen the hair, it thickens the hair as well, filling the cuticle and priming hair for styling. Although Repair Serum would work well as it is lightweight and strengthens and conditions hair.

                        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.
