Keratin Hair Treatment: The Real Pros + Cons
Celebrity makeup artist Christina Flach shares expert keratin hair treatment tips for smooth, frizz-free, healthy hair in Women Fitness Magazine.
“Keratin shouldn’t force your hair into something it’s not — it should make your natural texture smoother, healthier, and easier to live with.” — Christina Flach
Smooth, glossy hair is never one-size-fits-all — it’s about choosing what works for your hair, not against it.
Keratin treatments have become one of the most requested solutions for achieving smoother, shinier, more manageable hair. But with so many formulas out there — from Brazilian Blowouts to express keratin to full straightening systems — it’s essential to choose the right treatment for your hair type, lifestyle, and long-term hair health..
As a celebrity makeup artist working on-camera talent, athletes, TV hosts, and editorial shoots, I see every texture respond differently to keratin. When chosen correctly, keratin can be life-changing. When chosen incorrectly, it can flatten, dry, or overwhelm the hair.
Types of Keratin Treatments
Brazilian Blowout — Best for frizzy, wavy, or curly hair that wants smoothness but still wants movement. Lasts 3–4 months.
Traditional Keratin — Best for thick, coarse, or very frizzy hair. Stronger smoothing and straightening. Lasts 4–6 months.
Express Keratin — Best for fine or mildly frizzy hair needing a lightweight refresh. Lasts 6–8 weeks.
Who Should Get Keratin?
Great for anyone battling frizz, humidity, or long styling times. Avoid if pregnant, if hair is severely over-processed, or if you love big volume.
Pros: eliminates frizz, adds shine, cuts styling time in half, protects color-treated hair.
Cons: some formulas release fumes, can reduce volume, requires 24–48 hours of no washing after treatment.
Christina’s Top Tips
Use sulfate-free shampoo, deep condition weekly, sleep on a silk pillowcase, and don’t tie hair for 48 hours after treatment.
