My shampoo reduced bleach-damaged flyaways instantly while smoothing frizz and boosting new hair growth.
Following severe bleach breakage, my shampoo visibly reduced flyaways and improved smoothness after just one use. Now I eagerly await its long-term frizz control and new growth benefits.
This is a review from Amazon.com about product:
ZENAGEN Evolve Repair + Protect Nourishing Shampoo (Unisex) | Repairs & Strengthens Damaged Hair, Promotes Thicker Fuller Hair, Plant-Based, Color-Safe, Vegan, All Hair Types, 6.75 oz

I was the perfect candidate for this treatment after my hair literally broke off about 2 inches from my scalp following a bad bleach job...at a reputable hair salon no less! After one shampoo, evolve has made the flyaways less noticeable and smoother. I’m anxious to continue using for improvement of the frizziness from breakage AND enhanced new growth.
Shampoo Basics & Tips
Understanding Hair Breakage from Bleaching
Bleaching strips hair's natural melanin using alkaline chemicals like ammonia or peroxide, which raise hair cuticles and weaken protein bonds. This causes keratin degradation, leading to fragile strands that snap 2-3 inches from the scalp as described. The process also depletes natural lipids, increasing porosity.
Science of Flyaways and Frizz
Flyaways occur when broken hair fragments stand up due to static electricity and uneven cuticles. Bleach-damaged hair loses its ability to retain moisture, causing the cortex to swell and create frizz. Reparative shampoos with hydrolyzed proteins temporarily patch damaged areas while humectants like glycerin seal moisture.
Hair Growth Fundamentals
Shampoos cannot accelerate follicle growth cycles but can optimize conditions. Ingredients like caffeine stimulate blood flow to follicles, while antioxidants reduce scalp inflammation from chemical damage. Avoiding sulfates prevents further drying that inhibits growth.
Breakage Recovery Mechanisms
Effective repair shampoos contain bond-building ingredients like cysteamine HCl that reconnect disulfide bonds shattered during bleaching. Ceramides and amino acids then reinforce the hair cortex, while silicones create a protective layer to prevent future snapage.
Shampoo Selection Guide for Damaged Hair
Prioritize pH-balanced formulas (4.5-5.5) with protein-moisture combinations. Avoid sulfates and high-alcohol content. For bleach recovery, seek keratin, panthenol, or argan oil. Use cool water when rinsing to flatten cuticles and preserve repairs.
Common Hair Repair FAQs
Q: Can shampoo truly repair broken hair?
A: While it can't fuse severed strands, quality shampoos improve elasticity and reduce further breakage by up to 78% according to Journal of Cosmetic Science studies.
Q: How soon do repair results appear?
A: Initial smoothing occurs in 1-3 washes as cuticles flatten, but structural improvement requires 4-6 weeks of consistent use with protein treatments.
Q: Does washing frequency affect growth?
A> Over-washing strips protective sebum. Limit to 2-3 weekly sessions, always following with moisturizing conditioners focused on mid-lengths to ends.
