Silicone-Free Hair Treatment Mask Formula for Soft, Straight Hair

Hello!

Regarding your request for a silicone-free hair treatment formula to achieve straight, soft hair like a salon treatment, used as a post-shampoo mask without leaving residue on the scalp, you can use the base formula previously recommended by the staff. This formula is indeed silicone-free.

The base formula consists of:

• Water 86%
• Cetyl Alcohol 8% (Helps thicken the formula and softens hair)
• BTAC (Behentrimonium Chloride) 2% and CTAC (Cetrimonium Chloride) 1% (Cationic conditioning agents that help detangle and soften hair)
• Propylene Glycol 1% (Helps retain moisture)
• Pure Keratin 1% (Protein that helps nourish and strengthen hair)
• Phenoxyethanol SA 1% (Preservative)

How to use: Apply after shampooing, leave on for approximately 10-15 minutes, then rinse off.

If you wish to further enhance the coating and smoothing effect while remaining silicone-free, you can consider adding Poly-Conditioner Pro (30000 mPa.s) (e.g., at a rate of 1-3%). This is a polymer-based ingredient that effectively conditions hair, provides softness and slip, and reduces static electricity.

This formula will help nourish and condition your hair to appear straighter and softer.
