BKT is the best option

You can't beat Brazilian. It has formaldehyde which is a suspected carcinogen, but if you want results that are astounding and last, its really your best bet. I tried both Brazilian Keratin Treatment and Coppola Complex and truthfully, BKT win hands down. It made my hair smoother, softer, shinier and lasted longer than Coppola. After the former my hair was shinier, but not much smoother or softer, and it definitely didn't last as long as BKT.

Aldehyde is also dangerous like formaldehyde, so if your desperate for better hair you might as well just go along with BKT right?

That's my two cents.
