This booking is for the **Kerasilk smoothing system**, tailored for hair below shoulder length, and takes 120 to 150 minutes at Timba in Cardiff. ## What the treatment involves Below-shoulder hair needs extra time and product to smooth evenly from root to end, which is why this service runs longer than treatments for shorter lengths. The process typically includes: - A thorough cleanse to remove buildup and open the cuticle - Careful sectioning of the hair - Even application of the keratin smoothing formula through mid-lengths and ends - Blow-drying, followed by detailed flat-ironing to seal the keratin in place Our team, including senior stylists **Emma Stokes** and **Hannah James**, along with stylists **Lucy Osborne** and **Chloe Phillips**, can talk through the process and tailor the number of flat-iron passes to your hair type and desired result. ## Who it suits This treatment works well for most hair types, including wavy, curly, frizzy, or chemically processed hair. It's worth considering if you want: - Noticeably less frizz and easier everyday styling - Softer, shinier hair without permanently altering your natural texture - A treatment that gradually fades rather than restructures the hair If you like to wear your hair curly, let your stylist know you want to reduce frizz and bulk while keeping some natural movement, so they can adjust the amount of product and heat used. ## What to expect afterwards Results usually last a few months, though this varies by hair type and aftercare. Coarser or more resistant hair may need more passes, while fine hair tends to smooth more quickly. - Avoid washing or tying hair back for the first 72 hours - Switch to sulfate-free, keratin-friendly shampoo and conditioner afterwards - Avoid strong clarifying shampoos, chlorine, and saltwater to help the treatment last - Book a consultation first if hair is very damaged or over-processed, or if you have respiratory sensitivities, so we can discuss suitable formulas and salon ventilation ## How it compares Keratin smoothing is not the same as permanent straightening. It doesn't break and reform the hair's internal bonds, so your natural texture returns gradually as the treatment fades and new hair grows in. For clients wanting ongoing frizz control, repeat treatments a few times a year help maintain results, particularly for longer hair that's more exposed to everyday styling and environmental stress.

This service typically takes 120 to 150 minutes, as longer hair needs more time for sectioning, application, and flat-ironing. How much does it cost? Pricing for this service ranges from £0 to £199 depending on hair length and condition; your stylist will confirm the exact price at consultation. Will it make my hair completely straight? No, keratin smoothing reduces frizz and curl by up to 90 to 95% but doesn't permanently alter your natural texture, so some movement usually remains. How long do results last? Results commonly last around 3 to 5 months, gradually fading as hair is washed and grows out, though this varies by hair type and aftercare. What aftercare is needed? Avoid washing or tying your hair back for 72 hours after treatment, then switch to sulfate-free, keratin-friendly shampoo and conditioner and avoid strong clarifying products or chlorine. Can I still wear my hair curly afterwards? Yes, tell your stylist you want to keep some curl and they can adjust the amount of product and flat-iron passes to reduce frizz without removing all texture. Is this treatment suitable for damaged or colour-treated hair? It can be, but very damaged or over-processed hair may need a gentler approach; a consultation helps determine if it's the right fit for your hair's condition. Should I get colour done before or after this treatment? Colour services are generally best done before a keratin treatment, as the process can slightly alter or brighten colour, especially on blonde hair. Is this a permanent straightening treatment? No, it's different from permanent straightening or relaxers; it smooths and seals the cuticle temporarily rather than restructuring the hair's internal bonds.
