I swear by Virtue. Everything is infused with keratin and then you get the added bonus of what you want in a product eg smoothing/volume/curl etc.
Love it so much I got the salon size bottles and I had dark brown hair bleached platinum blonde when I started!!!
And minimal heat bb, we love a good leave in product (try their all in one) and air dry as much as you can ❤️
They also have an amaaazing scalp range which might be up your alley!
