Q&A

Do you use this product instead of the leave in conditioner since it is also a heat protectant. Also does it work well to hold curled or flat ironed styles?
Hi Lisa! Great question! The Thickening Spray does offer heat protection up to 450°F, but it's not a replacement for the Leave In Conditioner since it doesn't provide the same detangling, hydration, or frizz-fighting benefits. For best results, we recommend using both! Apply the Leave In Conditioner first, then follow with the Thickening Spray before heat styling. :)
Do I need to blow dry/heat to activate this? Can it natural dry and work? ( i have curly hair and would prefer no heat)
Hi Gigi, Yes, we recommend you to blow dry your hair for best result or heat style for maximum thickness. Tip: Blow-dry your hair using a round brush or by lifting the roots with your fingers. You may also find the full instructions directly on the product page. Hope this helps!
