Stephen’s Pro Tips


My go-to product to seal & protect hair. Get maximum results when applied sparingly to wet or damp hair. Use to style your hair from the bottom and move up to mid shaft to smooth and define ends. Hair looks refined and smooth, defined and polished and totally weightless. Perfect for all hair types.


Prestyling Must have for ALL hair types! For even distribution & best results, pump 1-2 squirts, depending on hair thickness and texture, into palm of hands and gently rub together creating a warming effect. Apply evenly to damp hair. The best leave-in styling tool for anyone who wants to embrace their natural curl and texture. Hair always looks soft shiny. Layer with Style Memory Lotion for added smooth, silky hair.


For overall equal distribution turn your head over and press into all the ends particularly for layered hair.


When you use each product or layer multiple products they should always be comped through - this tip applies to ALL. For curly hair, use Concentrated Hair Serum, follow with Style Memory Gel on wet hair, go to bed and wake up to beautifully defined curls.


This is the one essential product that balances the PH in your hair to counteract the effects of different water types.
