HASK Keratin Protein Smoothing Shampoo — 12 fl oz, Sulfate-Free Frizz Control & Shine

This lightweight shampoo cleanses hair while delivering keratin proteins that help smooth the cuticle and improve manageability. Formulated without sulfates, parabens, phthalates, gluten, alcohol, or artificial colors, it’s aimed at strengthening strands and taming unruly texture without stripping color or moisture. The invigorating scent makes everyday washing feel like a simple salon refresh.

How does this shampoo reduce frizz and resist humidity?

The formula contains hydrolyzed keratin, a protein fragment that adheres to weakened areas of the hair shaft to help smooth the surface. Smoother cuticles reflect more light, appear shinier, and are less prone to catching airborne moisture that creates frizz. Regular use helps maintain a sleeker look between styling sessions.

• Hydrolyzed keratin for cuticle smoothing
• Gentle cleansing removes buildup without over-drying
• Sulfate-free base minimizes additional roughening of the hair surface

Will it work on color-treated or chemically processed hair?

Yes — the gentle, sulfate-free formula cleans without stripping color or harshly removing treatments. Keratin fragments help reinforce compromised areas from coloring, bleaching, or heat styling, improving manageability and appearance over time. For best results, pair it with the HASK Keratin Protein Smoothing Conditioner.

• Safe for color-treated hair when used as directed
• Supports damaged strands with protein replenishment
• Leaves hair softer and easier to comb after rinsing

How should I use it in my routine for optimal results?

Apply to wet hair, lather gently from roots to ends, then rinse thoroughly; repeat if hair is heavily soiled or product-laden. Follow with HASK Keratin Protein Smoothing Conditioner to lock in moisture and enhance smoothing. Use regularly in place of harsh shampoos to maintain reduced frizz and improved shine.

• Wet hair thoroughly before applying a quarter-sized amount or more for long hair
• Massage into scalp and length, then rinse; repeat if needed
• Finish with the matching conditioner for best smoothing performance

Is this product formulated for sensitive scalps or specific ingredients to avoid?

The shampoo avoids common irritants like sulfates, parabens, phthalates, gluten, alcohol, and artificial dyes, making it a milder option for many users. However, individual sensitivities vary — patch testing a small area or checking ingredient lists is recommended if you have known allergies. It’s designed to balance effective cleansing with a gentler profile.

• Free from sulfates, parabens, phthalates, gluten, alcohol, and artificial colors
• Milder surfactant system than traditional sulfate shampoos
• Not a medical product; consult a dermatologist for scalp conditions

Who is this for: HASK Keratin Protein Smoothing Shampoo is made for people with frizzy, dry, damaged, or over-processed hair who want to reduce humidity-induced puffiness, improve shine, and maintain color integrity.

If you seek salon-style manageability without harsh cleansers, this 12 fl oz bottle fits into weekly or daily haircare schedules depending on your styling needs.
