Nisim Hair Growth Shampoo & Conditioner Duo — Biotin & Amino Acid Formula, Sulfate-Free, Clinically Studied

Nisim F.A.S.T. Shampoo & Conditioner is a daily-use duo formulated to support faster hair growth, strengthen strands, and improve shine with a biotin- and amino-acid–rich AVP Complex.

The two-step system combines a gentle, sulfate-free cleansing shampoo with a moisturizing conditioner designed to be used together. Backed by a 12-week clinical study, the formula pairs 8 amino acids, biotin, niacinamide and panthenol to nourish the scalp and help reinforce hair fibers. It’s designed for a wide range of hair concerns from thinning and postpartum shedding to color-treated and chemically processed hair.

How does this duo help support faster hair growth?

When used daily as a pair, the shampoo cleanses without stripping moisture while the conditioner helps seal and strengthen each strand. The AVP Complex focuses on delivering amino acids and vitamins that support the hair’s structure and visible fullness over time.

• Clinically studied over 12 weeks for comparative growth improvement
• Contains 8 amino acids that target keratin-building blocks
• Biotin and niacinamide to support scalp health and fiber resilience
• Daily use recommended for consistent results starting around six weeks

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

Yes — the formula is sulfate-free, paraben-free, vegan, and formulated to be safe on color-treated and chemically processed hair. It’s lightweight enough for finer types yet nourishing enough for thicker, curlier textures, making it versatile across hair patterns.

• Safe for dyed and chemically-treated hair
• Sulfate-free cleansing to protect color and moisture
• Trusted on textures from fine straight to 4C coils
• Cruelty-free and vegan ingredients

How should I use the F.A.S.T. Shampoo & Conditioner for best results?

Use the shampoo to thoroughly cleanse the scalp and hair, then follow with the conditioner focusing on mid-lengths to ends. For the clinical regimen, apply daily and maintain consistent use; improvements were measured at six weeks and through a 12-week study period.

• Wet hair, massage shampoo into scalp and rinse thoroughly
• Apply conditioner from mid-length to ends, detangle gently, then rinse
• Daily use recommended; follow through at least 6–12 weeks for visible change
• Compatible with styling and treatment routines

What performance and sensory benefits will I notice?

Beyond supporting growth and strength, the system is formulated to leave hair visibly shinier and feeling softer with improved slip. In clinical settings, most participants reported enhanced shine and nourishment after regular use.
