Keratin treatments simply laminate the hair. Our product penetrates the hair and works on the inside. Chemical relaxers break disulphide bonds - our product does not break any bonds - in fact it adds new bonds which lock the hair in a straight position. 
Yes. It does not damage the hair and does not contain any harmful chemicals like formaldehyde, ammonia or carbocysteine. Our product has been dermatologically tested.
In general, yes. There is nothing harmful in our products. However, preganacy is a sensitive time, therefore, before the treatment show the ingredients list to your doctor and ask if you can have the treatment. You can go ahead if they agree. 
Yes! We tested our products even on 4C afro hair. Our product effectively straightens all hair types. 
No. It will not damage your hair. It will make it look healthier and stronger. The only potential damage can come from setting the temperature of the hair straightening iron or doing too many passes but the product itself will not damage your hair.
Yes. The product works on any hair type. The only thing to be mindful of is warming of the hair. This is not from the product but from the heat of the straightener. Simply reduce your temperature and increase your passes. You can apply toner after 5 days!
Yes and even longer. Your customer will come in for root touch up before the product washes out. The longest we have seen it last is even 12 months.
