Keratin treatment is often considered a top solution for frizzy, unmanageable hair. But how do you choose between this and hair smoothening? This comparison explores both treatments in depth so you can make an informed decision.
What Is Keratin Treatment?
Keratin treatment is a semi-permanent salon procedure that infuses protein into the hair shaft. At the start, keratin treatment helps repair damage, reduce frizz, and enhance shine while maintaining your hair’s natural texture. Unlike straightening, it leaves you with manageable waves or curls and lasts two to six months. Though the initial cost is higher than smoothening, it saves time on styling and protects hair over the long term. For the best outcome, use sulfate-free products and follow strict aftercare to maintain the sleek, glossy result.
What Is Hair Smoothening?
Smoothening, often known as chemical rebonding or relaxing, uses strong chemicals to break and restructure the natural bonds of your hair. The outcome is ultra-straight, glossy hair that resists humidity and frizz for four to five months. Unlike keratin, smoothening does not repair hair; instead, it changes its internal structure. This can lead to brittleness or dryness over time. Although the initial cost is lower, frequent touch-ups are needed, and new hair growth may contrast noticeably with treated sections.
A common user experience shared online states:
“Keratin is a healthier option than smoothening, but it doesn’t last as long.”
If you’re looking for a dramatic straight look and are willing to maintain it with regular care, smoothening is an effective choice—but be mindful of long-term effects.
Core Benefits of Keratin Treatment
- Restores damaged strands by sealing cuticles with protein, reducing breakage
- Minimizes frizz and adds natural-looking shine
- Maintains flexible styling—preserves waves or curls
- Protects hair from UV rays, pollution, and environmental damage
- Saves time on daily styling and limits heat exposure
Risks and Side Effects
- Some keratin treatments may contain formaldehyde; choose formaldehyde-free options for safety
- Requires a strict aftercare routine, including no washing or tying hair for 72 hours
- Excessive heat during application can damage hair if not done properly
- Overuse may result in heavy or oily hair texture
Smoothening vs. Keratin: Side-by-Side Comparison
| Feature | Keratin Treatment | Hair Smoothening |
|---|---|---|
| Result | Smooth, shiny, healthy waves or curls | Sleek, ultra-straight finish |
| Duration | 2–6 months | 4–5 months |
| Hair Health | Strengthens with protein | May lead to dryness or breakage |
| Cost | Higher upfront, fewer touch-ups | Lower initial cost, more frequent visits |
| Aftercare | Requires sulfate-free care, no manipulation | Standard care, occasional trims |
Who Should Choose Which?
- Keratin treatment is suitable for people who want healthier, low-maintenance hair that maintains its natural style while minimizing frizz.
- Smoothening is a good choice for those looking for straight hair on a budget, even if it means managing long-term maintenance and potential dryness.
Real-Life Reviews and Testimonials
Several YouTubers and bloggers have compared both treatments. Many prefer keratin for its natural feel, flexibility, and gentler approach. One YouTuber stated she preferred the smoother, flexible finish of keratin over her previous smoothening experience, which resulted in dryness.
Another review highlighted the differences in cost, upkeep, and impact on hair health, suggesting that keratin treatment, while more expensive initially, provides better value over time due to reduced maintenance and improved hair quality.
Long-Term Investment Overview
- Cost per month: Keratin appears more expensive upfront but saves money in styling and aftercare
- Hair quality: Keratin strengthens and protects; smoothening weakens internal bonds
- Appearance during regrowth: Keratin fades subtly; smoothening often creates a visible line between treated and untreated hair
Tips for Best Results
- Choose formaldehyde-free keratin formulas and visit a salon with proper ventilation
- Follow aftercare: avoid washing, tying, or applying pressure for three days
- Limit treatments to no more than three times a year
- Use UV and heat protectants daily
- Consult with a hair professional to customize treatment based on your hair type and goals
Final Verdict: Which One Is Worth It?
Keratin treatment stands out for its ability to enhance long-term hair health, maintain flexible styling options, and create a glossy, natural appearance. It is a better investment if you are focused on hair care and sustainability.
Smoothening, although cheaper at the start, requires more frequent maintenance and carries a higher risk of long-term damage. If budget is a primary concern and you’re committed to upkeep, it can be a suitable choice.
