BIOLOGIC PERM HAS BEEN FOR 15 YEARS, THE TOP PRODUCT OF PREVIA PROFESSIONAL RANGE.
AN EXCELLENT SUCCESS, TREASURED IN A FORMULA WITH NATURAL ACTIVE PRINCIPLES AND A PLEASANT SCENT.
BIOLOGIC PERM ALLOWS CREATING FLEXIBLE, SOFT, SHINY AND HEALTHY CURLS THANKS TO THE USE OF SELECTED AND NATURAL RAW MATERIALS, WHICH GUARANTEE A PERFECT WAVING ACTION AND AT THE SAME TIME, HYDRATION AND PROTECTION OF YOUR SKIN AND HAIR.
ACTIVE PRINCIPLES:
The sugar softens the action of the waving liquid on the hair.
Soya’s hydrolyzed proteins perform a deep revitalizing action.
The amino acids from Marine Collagen and Keratin, which are similar to the hair in terms of nature and structure, guarantee the right nutrients, and maintain the capillary fibre resistant and flexible.
The hydrating and conditioning action is also fulfilled during the application phases of the Neutralising Liquid with the action of Polyquaternium 6, which acts in perfect synergy with the waving liquid, developing a long lasting conditioning and hydrating effect, thus giving the hair exceptional softness and shine.
INSTRUCTIONS FOR USE:
Shampoo your hair without rubbing the scalp, so as to preserve intact the hydrolipid layer. Rinse and dry with a towel.
Roll up the curlers, paying attention at the excessive traction of the elastic bands. Fill each curler with the Waving Liquid, starting from the back of your head until the front. Leave for 5/30 minutes with no heat, and 5/15 minutes with heat.
The setting times vary according to the structure and strength of the hair to treat.
Cover your hair with a proper cap to obtain the best result in terms of hydration and elasticity.
Select some test curlers in different parts of your head to verify the waviness.
Once the setting time has elapsed, rinse thoroughly with warm/hot water each curler, eliminating the Waiving Liquid completely. Dry the curlers with a towel and fill all curlers with the Neutralising liquid. Leave for 5 minutes, do not rinse and unroll the curlers without straitening your hair.
Apply the remaining Neutralising liquid on the hair and ends without brushing. Leave for 5 minutes and rise thoroughly.
Apply suitable Shampoo and Conditioner. ( Previa pH )
