Fergal Doyle Hair does not offer perms: our Bristol salons specialise in colour and cutting. If you are weighing up a perm, you still deserve straightforward answers about the commitment, cost and alternatives. Here is a practical starting point before speaking to a salon that specialises in perming.
How long does a perm last?
Expect the visible result to last roughly three to six months, although your starting texture, chosen curl and homecare all matter. A loose wave may soften sooner than a tighter curl. Rush’s guide to perm longevity gives three to six months as a general range and explains why results vary.
“Permanent” does not mean your hair will look exactly the same indefinitely. The treated lengths have been chemically changed, while new hair grows in with your original texture. Over time, the curl can loosen and the contrast at the roots becomes more noticeable. Growing it out or cutting it away is different from simply washing out a temporary style.
Ask your perming specialist what the result is likely to look like after several months, not just on the day. Take photographs of both the fresh curl you like and the softer look you would be comfortable maintaining.
How long does a perm take?
Allow around two to four hours as a broad planning guide, rather than squeezing it into a lunch break. Taylor Taylor London publishes a two-to-four-hour appointment guide. Wisteria Avenue’s spiral-perm guide allows around two-and-a-half to three-and-a-half hours.
The appointment involves more than leaving a solution to develop. Hair needs assessing, sectioning and winding, followed by processing, rinsing and neutralising. Longer or denser hair, smaller sections and a more detailed curl pattern can change the time needed.
Check whether the quoted slot includes a consultation, cut and finish. A separate consultation may be required before the treatment date. Only the salon doing your perm can confirm your actual appointment length after discussing your hair history.
How much does a perm cost in the UK?
Published UK examples span roughly £60 to £275 or more. That is an illustrative range, not a national average or an FDH price: we do not sell this service. Location, hair length, technique, stylist and what is included all affect the quote.
For context, We Are Salon’s published 2025 price list lists short-hair perms at £60–£80 and long-hair perms at £75–£105. Wisteria Avenue advertises spiral perms from £95. Taylor Taylor London lists starting prices of £195, £245 and £275 for different lengths and curl requirements. These published examples were checked on 14 October 2026; confirm current prices directly before booking.
Ask for a complete quote, including any cut, finish and recommended aftercare. A low starting price is not necessarily the total you will pay, and the cheapest option is not automatically the best match for your hair.
Is a perm worth it?
A perm can be appealing if you want a lasting change of texture and enjoy wearing waves or curls most days. It may reduce how often you reach for a curling tong, but it does not remove the need for styling, conditioning or maintenance.
The trade-offs are chemical processing, a growing-out period and the possibility that the result will not suit your hair’s condition. Bring a complete colour and treatment history to a specialist consultation, including home colour and previous straightening. Ask what is realistically achievable rather than assuming an inspiration photograph will translate exactly.
Our own approach is explained in why we don’t offer perms at Fergal Doyle Hair. Choosing a different service can be the better decision for your particular hair and priorities.
Want curls without a perm?
If your hair already has waves or curls, Evie can help you explore a curl-friendly cut and a styling routine that works with your natural pattern. Shape, product choice and drying technique can make existing texture easier to manage. A haircut will not create permanent curls in naturally straight hair.
For straight hair, temporary waves or a styled finish may suit you better if you want flexibility rather than a chemical change. Explore our Bristol curly-hair guide, meet Evie, or arrange a consultation to discuss your starting point, inspiration and daily routine.
