Which product are best for my extensions? By Hair Extension AngelsOctober 27, 20160 Back to Home Hair Extension Angels recommend to use all the products in a set on the hair. Please do not apply any of them too close to the root of the scalp. These products have a very rich consistency, if used too much, can create extra build up, so hair will have to be washed sooner then it has to be. so please use accordingly. Out product set has to be applied on the wet hair, so when heat is used, it activated the nutrients in the formula and gives the hair the best look possible. Back to Home
