Care Straight Treatment — Deep Conditioning for Lasting Straight-Hair Results

Where the shampoo begins the work, the STRAINIA Care Straight Treatment completes it. Applied after cleansing, this rich conditioning treatment penetrates the hair shaft to deliver deep moisture balance — targeting the uneven internal moisture distribution that STRAINIA identifies as the root cause of distortion, waviness and frizz.

Formulated with a sophisticated blend of silicones, ceramides, keratin and lactone actives, it leaves hair noticeably smoother, softer and more responsive to styling — making every blow-dry and brush-out easier and more effective. Use it daily as part of the complete STRAINIA Care Straight routine for cumulative, lasting results.

• Hydroxypropyltrimonium Hydrolysed Keratin (Wool) — Repairs and reinforces the hair structure from within
