Keratin Smoothing (2nd Phase)

From £150
60 - 90 mins

This is the finishing stage of your keratin smoothing journey. Once the keratin formula has been applied to your hair, we use precision heat styling to seal it into every strand, locking in that smooth, shiny, frizz-free finish you're after. It's a focused appointment that perfects the results and ensures they last as long as possible.

What Happens During the 2nd Phase

This visit is all about sealing and perfecting. We'll work through your hair in small sections with a high-heat flat iron, making multiple passes to lock the keratin deep into the cuticle. The heat activates and sets the treatment, transforming frizz into smoothness and adding serious shine. Depending on your hair's length and thickness, expect to be with us for around 60 to 90 minutes. Our stylists adjust the iron temperature and technique to suit your hair type and condition, so whether your hair is fine, coloured, or naturally thick and curly, you're in safe hands.

The Results You Can Expect

Once we're done, you'll notice:

  • Reduced frizz – even in damp or humid weather
  • Improved manageability – hair that's easier to brush, style and live with
  • Faster blow-drying – less time wrestling with the hairdryer
  • Enhanced shine – that glossy, healthy-looking finish
  • Smoother texture – curls become looser and more defined rather than disappearing completely

Results typically last 2 to 6 months, depending on your hair type, how often you wash it, and how well you follow the aftercare advice. It's a semi-permanent smoothing treatment, not a permanent straightener, so it gradually washes out as new hair grows in.

Aftercare: The First 72 Hours Matter

To get the most from your keratin smoothing, you'll need to follow some strict rules for the first three days:

  • No washing or wetting your hair – keep it completely dry
  • Wear your hair down and straight – avoid clips, hairbands, hats or anything that creases it
  • No workouts that cause heavy sweating – moisture is the enemy during this setting period
  • Avoid getting caught in the rain – plan ahead or keep an umbrella handy

After that initial period, switch to sulfate-free and sodium-chloride-free shampoos and conditioners. These gentler formulas won't strip the keratin out prematurely. To stretch your results even further, wash less often (dry shampoo is your friend), and if you swim regularly, protect your hair from chlorine and salt water with a good layer of conditioner or a swim cap.

Who It's For and What to Consider

Keratin smoothing suits most hair types, especially if you're battling frizz, spending ages blow-drying, or just want smoother, shinier hair without committing to permanent straightening. Because this phase involves high heat and chemical formulas, it's important to chat with your stylist first if your hair is very damaged, over-processed, or fragile. Our team will assess your hair's condition and adjust the approach to keep it healthy. If you love your strong curls exactly as they are, keratin smoothing might not be the right fit – it's designed to loosen texture and reduce frizz, not preserve tight curl patterns. And if you're pregnant or have a sensitive scalp, do mention it during your consultation so we can discuss the best options for you.

Frequently Asked Questions

How much does the Keratin Smoothing 2nd Phase cost?
The service starts from £150, depending on your hair's length and thickness. We'll confirm the exact price during your consultation.
How long does the appointment take?
Plan for 60 to 90 minutes. The time varies depending on how much hair you have and its condition.
What's the difference between the 2nd Phase and a full keratin treatment?
The 2nd Phase focuses on sealing and finishing the keratin that was applied earlier. It's quicker than a full treatment because the formula application and processing have already been done.
Can I wash my hair after the appointment?
No, you'll need to keep your hair completely dry for 72 hours after the treatment. This allows the keratin to fully set and gives you the longest-lasting results.
What happens if my hair gets wet during the 72-hour period?
Moisture can disrupt the setting process and reduce how long the smoothing lasts. If it does get wet, gently blow-dry it straight as soon as possible and avoid any further water exposure.
How long will the results last?
Typically 2 to 6 months, depending on your hair type, how often you wash it, and whether you use the right aftercare products. Sulfate-free shampoos help extend the results.
Will my hair be completely straight after keratin smoothing?
Not necessarily. Keratin smoothing reduces frizz and loosens curls, making hair smoother and easier to manage, but it's not a permanent straightener. Very curly hair usually becomes softer and more defined rather than pin-straight.
Can I still use heat tools after the treatment?
Yes, you can straighten or curl your hair as usual, and you'll find it much quicker and easier. Just keep using a heat protectant to maintain your hair's health.
Is keratin smoothing safe for coloured or bleached hair?
Yes, but it's important to let us know your hair's history during your consultation. We'll adjust the formula and heat settings to protect fragile or over-processed hair.
How soon can I have the treatment done again?
You can repeat keratin smoothing roughly every 3 to 4 months as the treatment wears off, as long as your hair is in good condition. We'll advise you on the best timing during your visit.
