What an horrible product and even worst customer service . For starters my hair is virgin no chemicals really healthy and long . I’m always trying new stuff to make my hair shinny or healthier so I order two packages of the keratin and she shampoo . I used it as directed and it burn my scalp and my hair I had to cut few inches . I send an email to rerun the product and after 4 days they answered me with the excuse that they do not accept returns if is because I didn’t like my results that I should used as directed ( I did ) they were so rude and condescending . Stay away from this product it is not natural as they said the odor tells you otherwise . Don’t spend your money on this .
