Beware of hair breakage

Perhaps this was an old bottle, but my stylist followed instructions that I looked up on YouTube. The newest video I could find was from 10 years ago. The end result, major hair breakage and shedding! To add insult to injury, I am unable to return this product.

No More Harsh Chemicals

I started using this product instead of getting a relaxer and I so happy with the outcome. I have stronger hair with less breakage.

Great effect on my hair

I had Cysteine complex done on my hair by a Loreal saloon in India while on a holiday during Christmas and it lasted till now after 10 weeks and it would probably last forever. I live in Sydney and the saloons don't use this product here so I ordered it from Amazon. I applied it myself and used a straightening iron after 20 minutes. The effect is great. It took less than one hour and the bottle will last me for over two years so I am saving thousands. Surprisingly it has taken away all the frizz and my hair looks naturally straight for the first time in my life my hair looks good and I can grow it. It has bounce and my hair never moved before. I swear this is the best product. I was lazy and used my hans a bit and it had no impact. For me the product is safe.

My hair was beautiful at first

BE CAREFUL WITH THIS PRODUCT. If used correctly, your hair will be fabulous. However, after you use any keratin product for a long time. It will eventually dry out your hair and turn it into straw. It will dry out your hair. I would only use it twice a year. Also, never put this product directly on your scalp. Follow the instructions, exactly - especially if you are not a licensed professional. If works, if it you use the product correctly and not frequently. My hair was beautiful at first. I dried it out and it broke off. Secondly, I damaged my hair follicles because I poured the product directly on my scalp. It look nearly TWO years for my hair to start growing back normal. Keratin treatments will eventually damage your hair after prolonged use.
