I have been loving two products from KMS lately which has really added extra oomph to my hair style. These products are Free Shape 2-in-1 styling + finishing spray and Add Volume root and body lift spray.
I use both of these after I have showered in towel dried hair (If it matters I use the turby towels which help my hair go super soft). I spray the Add Volume to my roots in sections and rub it in gently to really get the friction going, then I spray the Free Shape all over (I make sure I am spraying from a good distance away so the spray is evenly distributed) before blow drying my hair upside down.
This gives my hair big volume and bouncing waves- they are gorgeous and really last. The only downside is for the first day my hair is barely controllable due to the softness (I use Tresemme Volumizing Shampoo and Conditioner every other day) but otherwise these two are a killer combo. Highly suggested on this part of the internet.
