Acid Perm

£55 – £71.50
90 - 0 mins

An acid perm uses a milder, acid-balanced formula to create soft, natural-looking waves or curls without the harsher effects of traditional perms. It's particularly well-suited for coloured, highlighted, or delicate hair that needs a gentler approach, offering lasting texture and body with reduced risk of damage.

What to Expect During Your Acid Perm

Your appointment at our Weymouth salon begins with a consultation where we assess your hair's condition, discuss your desired curl size, and confirm suitability. The process typically includes:

  • Cleansing and sectioning your hair to remove any product buildup
  • Wrapping hair around perm rods sized to your preferred curl pattern—smaller for tighter curls, larger for loose waves
  • Applying the acid perm solution and monitoring processing time based on your hair texture
  • Rinsing and neutralising to fix the new curl shape in place
  • Styling to reveal your final texture, with the full service taking around 75-120 minutes depending on hair length and thickness

Who Is an Acid Perm Suited For?

Acid perms work beautifully for clients with coloured or chemically treated hair who want added movement without excessive stress on their strands. They're ideal if you're looking for:

  • Soft, natural-looking waves rather than tight ringlets
  • Added volume and body that reduces daily styling time
  • A gentler alternative to alkaline perms for fragile or fine hair
  • Lasting texture that works with your lifestyle and maintenance preferences

During your consultation, our stylists—including salon owner Nicki Cattel and director Hannah Tribe—will review your chemical history and ensure your hair is healthy enough for the service.

Aftercare and Maintaining Your Perm

To help your acid perm last 2-3 months with strong definition, follow these essential care steps:

  • Avoid washing for 24-48 hours after your appointment to let curls fully set
  • Use moisturising, sulphate-mild shampoos and conditioners designed for permed or curly hair
  • Apply leave-in conditioners or curl creams to keep hair hydrated and reduce frizz
  • Limit heat styling—air dry or use a diffuser on low to medium heat
  • Avoid chlorinated pools or salt water, or protect hair with a swim cap and post-swim conditioning
  • Book regular trims and deep conditioning treatments to maintain hair health

Styling Your Acid Perm

One of the benefits of an acid perm is its versatility. You can style your new texture in multiple ways depending on your mood:

  • Scrunch with mousse or curl cream for defined, bouncy curls
  • Diffuse on low heat for volume and soft waves
  • Brush out gently for a tousled, relaxed look with natural movement
  • Use minimal heat tools to preserve curl longevity and hair health

Your stylist will show you the best techniques for your specific curl pattern and lifestyle, ensuring you feel confident styling your perm at home in Weymouth and beyond.

Frequently Asked Questions

How much does an acid perm cost at Changing Grooms?
Our acid perm service is priced between £55 and £65, depending on your hair length, thickness, and complexity. A consultation will provide a more accurate quote tailored to your needs.
How long does an acid perm appointment take?
Most acid perm appointments take between 75 and 120 minutes, including consultation, wrapping, processing, neutralising, and styling. Longer or thicker hair may require additional time.
How long will my acid perm last?
An acid perm typically lasts 2-3 months with strong curl definition, gradually softening as your hair grows. Longevity depends on your hair type, aftercare routine, and exposure to heat or chlorine.
Can I get an acid perm if I have coloured hair?
Yes, acid perms are specifically designed to be gentler on coloured, highlighted, or chemically treated hair. However, you should disclose all recent treatments during your consultation so we can assess suitability and minimize damage risk.
What should I avoid after getting an acid perm?
Avoid washing your hair for 24-48 hours after your perm to allow curls to set fully. Also avoid tying hair tightly, using high heat tools, or swimming in chlorinated or salt water during the first few days.
Will an acid perm damage my hair?
Acid perms are gentler than alkaline perms, but any chemical service can increase dryness. Proper aftercare with moisturising products and regular conditioning treatments helps maintain healthy, resilient hair.
What's the difference between an acid perm and a regular perm?
Acid perms use a milder, lower-pH solution that's gentler on the hair cuticle, creating softer, looser waves or curls. Traditional alkaline perms use stronger formulas that produce tighter, bouncier curls but can be harsher on delicate or coloured hair.
Do I need a consultation before booking an acid perm?
Yes, we strongly recommend a pre-service consultation to assess your hair condition, discuss your goals, and determine if an acid perm is suitable. This ensures the best possible results and minimizes risk.
How should I care for my acid perm at home?
Use moisturising, sulphate-mild shampoos and conditioners designed for permed hair. Apply leave-in treatments regularly, limit heat styling, air dry or diffuse on low heat, and book periodic deep conditioning treatments to maintain curl and hair health.
Can I straighten my hair after getting an acid perm?
While you can occasionally straighten permed hair, frequent use of heat tools will relax curls faster and increase dryness. If you want flexibility between straight and curly styles, discuss your styling preferences during your consultation.
