Kerastraight is a semi-permanent keratin smoothing treatment that reduces frizz, softens curls and makes hair easier to manage, without the harsh chemicals of traditional relaxers. Suitable for most hair types—including coloured, bleached and afro hair—it delivers smoother, shinier results that last up to four months. Our stylists in Handcross tailor the treatment to your hair's needs, so you leave with healthy, polished hair that takes half the time to style at home.
More information
What to expect during your appointment
Your Kerastraight appointment takes around 2½ hours and involves:
- Deep cleanse shampoo to prepare the hair
- Sectioned application of the keratin formula
- Processing time under a cap, then a light rinse
- Moisture-lock step to seal in the treatment
- Full blow-dry and thorough straightening with irons in small sections—heat locks the keratin into the hair for lasting smoothness
Results are visible immediately: less frizz, more shine, and noticeably easier styling.
Who Kerastraight suits
This treatment works well if you:
- Want to cut blow-dry time in half and reduce daily heat styling
- Have frizzy, wavy or curly hair you'd like to soften and smooth
- Struggle with humidity or want low-maintenance, polished hair between salon visits
- Have coloured, highlighted or chemically treated hair—Kerastraight is formaldehyde-free and designed to be gentle
- Prefer a natural, moveable finish rather than poker-straight hair
Very curly or coily hair will become looser, smoother and less frizzy, though the result is typically soft waves rather than completely straight lengths unless you continue to blow-dry and iron regularly.
Aftercare and how long it lasts
Kerastraight is not permanent—your natural texture gradually returns over 3–4 months as the treatment wears off and new hair grows. To get the most from your service:
- Use sulphate-free, sodium chloride-free shampoos and conditioners—clarifying or harsh formulas will strip the treatment faster
- You can shampoo relatively soon after your appointment (often from 30 minutes onwards), unlike older keratin systems
- Heat styling is still possible, but you'll need less of it; many clients air-dry with minimal frizz
- Plan for a top-up every few months if you want to maintain the smoothness long term
Our team will recommend the best home-care products and talk you through realistic maintenance during your consultation.
Pricing and booking
Kerastraight is priced at £250–£300 depending on hair length and thickness, reflecting the time, skill and premium product involved. During your consultation we'll assess your hair history—any previous colouring, bleaching, relaxers or perms—and choose the most appropriate formula and technique. If you're pregnant, nursing or have a sensitive scalp, let us know so we can discuss suitability. Book by calling 01293 885882 or emailing consultations@aaron-russell.net.
