Keratin Treatment
Keratin treatment is a protein-based conditioning procedure that infuses concentrated keratin — the natural protein found in hair, skin, and nails — back into the hair shaft. Unlike smoothening, keratin does not permanently alter the hair's structure. Instead, it fills in gaps in the cuticle, creates a protective smoothing layer, and reduces frizz while maintaining your natural texture and movement. At AAINA Salon in Sadar, Lucknow, keratin treatment starts from ₹5,999 and takes approximately 120 minutes.
The process begins with a thorough hair assessment and strand test. Hair is cleansed with a clarifying shampoo to open the cuticles. The keratin solution is applied section by section, then sealed using a professional flat iron at a controlled temperature. This heat-sealing step bonds the keratin to the hair, creating a smooth, frizz-resistant coating. The result is hair that feels softer, looks shinier, and is significantly easier to manage — all while keeping your natural curl pattern and volume intact.
Benefits of Keratin Treatment
- ✦ Preserves natural hair texture and movement
- ✦ Excellent frizz control, even in humid climates
- ✦ Adds intense shine and softness
- ✦ Low damage risk — it is a conditioning treatment
- ✦ Can be repeated frequently without harm
- ✦ Reduces daily styling time significantly
- ✦ Suitable for curly, wavy, and frizzy hair types
Keratin is the ideal choice for anyone who loves their natural hair texture but wants it to be smoother, shinier, and more manageable. It is particularly popular among clients with curly or wavy hair who want frizz reduction without sacrificing their natural look. The treatment also strengthens hair over time, making it a health-conscious choice for long-term hair care.
Hair Smoothening
Hair smoothening is a chemical treatment that restructures the hair shaft to create a straighter, smoother appearance. It uses a smoothening cream that breaks the disulphide bonds in the hair, then a neutralizer reforms these bonds in a straighter configuration. This process permanently (until new hair grows) alters the hair texture from curly or wavy to straight. At AAINA Salon, smoothening starts from ₹5,499 and takes approximately 120 minutes.
The treatment begins with a consultation and strand test to determine hair suitability. Hair is deep-cleansed to remove buildup. The smoothening cream is applied and left to process for a specific duration based on hair texture and resistance. After processing, the hair is flat-ironed to set the straight pattern, then a neutralizer is applied to lock in the new structure. The result is sleek, pin-straight hair with a glossy finish that lasts for months.
Benefits of Hair Smoothening
- ✦ Achieves pin-straight, sleek hair
- ✦ Eliminates curl pattern for a straight look
- ✦ Long-lasting results (4–6 months)
- ✦ Dramatic reduction in daily styling time
- ✦ Smooth, glossy finish
- ✦ Effective on very curly or resistant hair
- ✦ Lower entry price than keratin
Smoothening is the preferred choice for clients who want a visibly straighter look and are comfortable with chemical processing. It is particularly effective for very curly or coarse hair that may not respond sufficiently to keratin alone. If your goal is sleek, straight hair with a polished finish, smoothening delivers the most dramatic transformation.
Detailed
Key
Differences
Natural Look vs Pin-Straight
This is the fundamental difference. Keratin gives you a natural, healthy version of your existing hair — smoother, less frizzy, more polished, but still recognisably yours. Smoothening transforms your hair into a straighter, sleeker version that looks noticeably different from your natural texture. The choice depends entirely on whether you want to enhance what you have or change it.
Chemical Process vs Protein Infusion
Keratin infuses protein into the hair — it adds to the hair without stripping or altering anything. Smoothening uses chemicals to break and reform the hair's internal bonds, which is a more invasive process. This chemical restructuring is why smoothening achieves straighter results but also carries a higher risk of damage.
Damage Risk
Keratin carries minimal damage risk — it strengthens hair over time. Smoothening, while safe when done professionally, involves stronger chemicals that can cause dryness, brittleness, or breakage if over-processed or if aftercare is neglected. For clients with already damaged or chemically treated hair, keratin is the safer option.
Repeat Frequency
Keratin can be safely repeated every 3–5 months without cumulative damage. Smoothening should be repeated with more caution — typically every 4–6 months — and only on new growth to avoid over-processing previously treated hair. This makes keratin a more sustainable long-term treatment option.
Curl Pattern Impact
Keratin loosens curl patterns slightly — curls become softer and more defined but remain present. Smoothening eliminates the curl pattern entirely, creating straight hair from root to tip. If you have tight curls and want to keep some curl definition, keratin is the better choice. If you want to completely straighten your hair, smoothening delivers that result.
Maintenance Intensity
Both require sulphate-free shampoo, but smoothening maintenance is more demanding. After smoothening, you may need to avoid tying hair, using clips, or exposing hair to moisture for the first few days. Keratin maintenance is simpler — sulphate-free products and minimal heat styling in the first week are the primary requirements.

Neither is universally better — it depends on the result you want. Keratin treatment preserves your natural texture while reducing frizz and adding shine, giving a more natural, bouncy look. Smoothening chemically alters the hair structure to create a straighter, sleeker appearance. If you want natural movement with less frizz, choose keratin.
