Sunpure Straight Keratin Treatment
I am a hairdresser and I have been using Sunpure Straight Brazilian Keratin Treatment. I've done a dozen or so treatments. I think this is a safe service. I checked the ingredients and called the manufacturers. As with all services I perform in the salon I am careful as to breathing in the fumes or contact with skin for my clients and myself. Because it uses Vanillin as a aldehyde and other natural ingredients like apple pulp it takes more time and work to apply into the hair, where as the stronger chemicals help melt the keratin into hair easier and faster.
No one yet has complained about it. It softens and conditions and makes the hair less frizzy and more manageable. I believe this treatment has no formaldehyde and I nor any clients I've done has had any adverse reactions to it.
