Cuts and styling

Bring examples of the length or finish you prefer and explain your everyday styling routine. Compare a wash and blow-dry with the cut, conditioning and straightening options in the menu.

03

Weaves and braids

Agree the style and any supplies with the provider. Hair is not included with the leave-out weave. Box braid extensions are priced at £90–£120, with the final price agreed at consultation.

There are 16 services across smoothing and conditioning, balayage and highlights, full-head colour, root tint and toner, cutting and blow-drying, plus a leave-out weave, cornrows with extensions and box braids extensions. Each service has a guide and listed price. Confirm availability, the complete appointment and product or supply requirements before booking.

The supplied menu lists keratin treatment at £130. Ask about the exact smoothing product, previous colour or chemical services, relevant checks, ventilation and what the appointment includes. The intended result and aftercare are product-specific. A smoothing service should not be presented as a medical treatment for hair loss or an active scalp condition.

Balayage is £140, full-head highlights £125, half-head highlights £95 and T-section highlights £70 on the supplied menu. Explain the placement and brightness you want and how you wear your hair. Ask which sections are included and whether toner or finishing is separate; the menu does not establish every package combination.

Full-head colour is £60, root tint £45 and toner £20. Discuss whether your goal concerns an all-over colour service, regrowth or a tone adjustment to suitable existing colour. These are different appointments. Ask the stylist what the proposed option can change and which other services, if any, are required.

Ask about the checks required for the exact product and service, and follow those instructions. An allergy alert procedure, a hair strand test and specialist diagnostic patch testing have different purposes. Disclose previous dye reactions, black henna tattoos and scalp symptoms. A test does not justify ignoring a reaction or guarantee that none will occur.

Men's hair cut is £20, wash and blow-dry £30, wash, cut and blow-dry £50, and wash, cut, blow-dry and straighten with an iron £60. Choose the service matching your request and confirm the finish and inclusions. Conditioning is a separate £25 listing; do not assume it is included.

Conditioning is listed at £25 and belongs to cosmetic hair care. Ask which product is proposed, what it is intended to do and how it fits your texture, processing history and routine. It should not be treated as diagnosis or medical treatment for persistent scalp symptoms or unexplained shedding. Mention those concerns before the service is arranged.

No. The £80 leave-out weave listing explicitly excludes hair. Confirm the type, length, quantity, preparation and suitability of the hair before buying it. Also ask about leave-out care, scalp access, maintenance and removal. The website does not establish a separate removal or maintenance price.

Straight-back cornrows with extensions are listed at £40. Confirm the pattern, size, length and materials you need to supply; the menu does not specify every extension inclusion. Ask how the style will be maintained and removed, and tell the stylist about previous soreness, breakage or thinning before installation.

Box braids extensions are listed at £90–£120 with the price agreed at consultation. Confirm how your chosen style fits that range, what is included and any supply requirements. The website does not invent a formula for size or length charges. Agree the complete plan and final price before proceeding.

Pain should not be accepted as a requirement of a secure style. AAD guidance identifies pain as a sign of excessive tightness, and repeated pulling can contribute to traction hair loss. Tell the stylist promptly and ask for reassessment. Persistent soreness, a rash or noticeable thinning warrants appropriate clinical advice.

The menu covers cosmetic cutting, colour, styling, treatments and extensions. It does not establish a medical hair-loss, transplant or hair-system replacement service. Persistent scalp symptoms or worrying shedding should be assessed appropriately. Dermatology guides may help prepare a conversation, and some concerns need GP or specialist care.
