What Is Keratin? The Science Behind the Treatment
Keratin is the primary structural protein that makes up your hair, skin and nails. Healthy hair contains up to 95% keratin — giving it strength, elasticity and natural shine. But daily exposure to heat styling, chemical treatments, harsh shampoos and Nagpur's humidity causes keratin to deplete, leaving hair frizzy, brittle and dull.
The Science
Each hair strand has an outer protective layer called the cuticle. When keratin depletes, the cuticle lifts — allowing moisture from the air to enter, causing frizz. A keratin treatment floods each strand with protein, smooths the cuticle flat and seals it — locking out humidity and restoring shine.
Why Hair Loses Keratin
Heat styling strips keratin at temperatures above 180°C. Chemical services (colouring, bleaching, perming) break down protein bonds. Sulphate shampoos, hard water and UV exposure all accelerate keratin loss — which is why most people experience progressively drier, frizzier hair over time.
Who It Works Best For
Keratin treatment is ideal for frizzy, coarse, thick or unmanageable hair. Nagpur's intense monsoon humidity and summer heat make it especially effective — it creates a protein barrier against moisture. It is not recommended for very fine or thin hair as it can add weight and reduce volume.
Formaldehyde-Free Options
7 Mirrors offers formaldehyde-free keratin treatments for clients who are sensitive to chemicals. These use alternative bonding agents to achieve similar smoothing results — ideal for those with chemical sensitivities. Just mention your preference when booking and we'll match you to the right formula.
Keratin Treatment Options at 7 Mirrors
Brazilian Keratin Treatment
The gold standard in keratin smoothing. Brazilian keratin deeply penetrates the hair shaft, eliminating frizz and adding intense shine. Results last 4-5 months. Ideal for thick, coarse or highly textured hair.
Soft Keratin Treatment
A gentler formula for fine or colour-treated hair. Soft keratin reduces frizz by 80% without fully straightening. Retains natural movement and body. Lasts 3-4 months. Safe for regular and chemically processed hair.
Express Keratin Treatment
A quick 90-minute version for those short on time. Results last 6-8 weeks and can be repeated. Great as a maintenance treatment between full keratin sessions or for light frizz control.
Nagpur Climate Benefits
Nagpur experiences extreme humidity in monsoon and dry heat in summer - both cause frizz and hair damage. Keratin treatment creates a protective protein shield around each strand, preventing humidity and heat from penetrating the hair shaft.
Aftercare for Keratin
Use sulphate-free shampoo, avoid chlorine and seawater, tie hair loosely and avoid washing for 48-72 hours after treatment. Monthly deep conditioning helps maintain results. Our team provides a complete aftercare guide at the salon.
Who Is It For?
Keratin is ideal for anyone with frizzy, wavy, curly or unmanageable hair. It works on natural hair, coloured hair and hair extensions. Not suitable for those with very short hair (under 3 inches) or freshly bleached hair.

Hair Colour & Keratin Treatment
Can you colour your hair and get keratin at the same visit? Here's what you need to know.
Colour First, Then Keratin
The correct sequence is always colour first, keratin second. Keratin seals the hair shaft — when applied after colour, it locks the colour molecules inside, significantly extending colour vibrancy and shine. This sequence is actually a benefit for coloured hair clients.
The Waiting Period
Wait at least 2–3 weeks after colouring before getting keratin. Fresh colour needs time to fully settle into the hair shaft. Applying keratin too soon can cause uneven absorption or strip colour pigments. Similarly, wait 2 weeks after keratin before your next colour service.
Can Keratin Fade Colour?
Applying keratin immediately over fresh colour can push pigments out as the treatment penetrates the hair shaft — which is why timing matters. At 7 Mirrors we always check your colour history before recommending treatment dates to ensure the safest and most effective outcome.
Keratin Treatment in Nagpur's Climate - Why It Works
Summer (March-June)
Nagpur summers bring extreme heat and humidity that causes frizz within minutes of stepping outside. Keratin treatments coat each hair strand in a protein film that repels moisture - the most effective solution for Nagpur's peak summer months.
Monsoon (July-September)
Rain and humidity are relentless during Nagpur's monsoon. Without keratin, hair absorbs moisture from the air constantly causing unmanageable volume. A keratin treatment applied before or during early monsoon dramatically reduces this effect.
All-Year Manageability
Even in cooler months, Nagpur's dust and pollution cause hair surface roughness. Keratin smoothens the cuticle layer, making hair easier to style, less prone to tangling, and visibly more shiny year-round.

Keratin Treatment: Results Timeline
Here's what to expect day-by-day and week-by-week after your keratin treatment at 7 Mirrors.
Day 1 — Treatment Day
Hair is washed, keratin applied, blown out and flat-ironed to seal. You leave the salon with noticeably smoother, shinier hair immediately. Avoid washing for 48–72 hours. Keep hair down, dry and avoid ties, clips or getting it wet in rain.
Week 1 — Hair Fully Settles
The keratin fully bonds to the hair shaft during the first week. After your first wash with sulphate-free shampoo, hair feels soft and smooth. This is when most clients see the full results — frizz dramatically reduced and drying time cut in half.
Month 1–2 — Peak Results
Hair is at its best during this period. Mornings are easier, styling time is reduced. Hair holds up well even in Nagpur's monsoon humidity. Use sulphate-free shampoo and avoid chlorinated pools to maintain results longer.
Month 3–4 — Time to Book Next Session
Results begin to gradually fade as keratin washes out naturally. Hair may show slight frizz returning. This is the ideal time to book your next session — results are still partially present, making the next treatment easier and often more effective.
