Shampoo Basics & Tips
Why Keratin Shampoos Enhance Hair Health
Keratin shampoos like GK contain proteins that reconstruct hair cuticles. When you get salon keratin treatments (smoothing/straightening procedures), these shampoos preserve results by replenishing keratin lost during chemical processing. They prevent frizz and breakage by filling gaps in the hair shaft.
Long-Term Shampoo Benefits Explained
Consistent use of protein-rich shampoos strengthens hair over time. Unlike harsh sulfates that strip natural oils, formulations like GK gently cleanse while depositing strengthening agents. This cumulative effect reduces split ends and maintains shine – explaining the reviewer's decade-long satisfaction.
Post-Treatment Hair Care Essentials
After keratin treatments, avoid sulfates and sodium chloride for 2 weeks. These ingredients degrade keratin bonds. Use pH-balanced (4.5-5.5) shampoos to keep cuticles sealed. Always follow with sulfate-free conditioners to lock in moisture and prolong treatment effects.
Identifying Truly Healthy Hair
Healthy hair shows elasticity (stretches 30% without breaking), reflects light uniformly, and sheds minimally (<100 strands/day). Protein/moisture balance is key – brittle hair needs keratin, while limp hair requires clarifying formulas. Regular trims prevent damage progression.
Shampoo Selection FAQs
Q: How often should I use keratin shampoo?
A: 2-3 times weekly for maintenance; daily if hair is severely damaged.
Q: Can keratin shampoos cause buildup?
A: Yes – alternate with clarifying shampoo monthly. Look for "hydrolyzed keratin" which absorbs better.
Q: Why pair shampoo with professional treatments?
A> Salon treatments penetrate deeper, while daily shampoos provide surface-level protection and extend results.
