How to Stop Frizzy Hair: The Best Salon Solutions for Summer Frizz

Searching for a frizzy hair treatment or keratin treatment in London? Summer humidity, unexpected rain showers, heat styling and UV exposure can all leave hair looking dry, fluffy and difficult to manage. At Haug London Haus in Fitzrovia, our hair specialists tackle frizz with personalised salon treatments designed to smooth, strengthen and hydrate the hair. Whether you're looking for a keratin blow dry, hair repair treatment, cryotherapy for hair or a professional scalp treatment, understanding what's causing your frizz is the first step towards healthier, smoother hair.

Why Does Hair Become Frizzy in Summer?

According to Haug London Haus co-founder and former British Colour Technician of the Year Siobhan Haug, frizz is usually a sign of dehydration.

"Frizzy hair is primarily hair that's dehydrated for a number of different reasons. We need the natural oils from our scalp to migrate down through the hair and keep it supple, but this can be harder on curly or thick hair types, causing them to be naturally a little more frizz prone. Frizz can also be due to overuse of heated styling equipment that causes the hair cuticle to become parched, leading to a potentially frizzy texture."

Summer weather can make matters worse. Hot temperatures, humid conditions and even getting caught in a summer rain shower can all cause hair to absorb excess moisture from the atmosphere. When this happens, the hair shaft swells, leading to flyaways, puffiness and loss of definition.

Hair that is already damaged, colour treated or naturally porous is often the most susceptible to frizz because the cuticle layer is less able to regulate moisture levels within the hair.

"The mistake many people make is assuming all frizz needs the same solution," explains Siobhan. "In reality, frizz can be caused by dehydration, humidity, UV exposure, scalp stress or damage, which is why we tailor treatments to the individual rather than reaching for a one-size-fits-all fix."

The Best Professional Anti-Frizz Hair Treatments in London

At Haug London Haus, our London hair specialists offer a range of professional hair treatments designed to tackle different causes of frizz while improving the overall health and condition of the hair.

Hair.TOXX Cryotherapy: Freeze your Frizz!

One of the newest anti-frizz treatments available at our Fitzrovia salon is Hair.TOXX Cryotherapy, a pioneering and award-winning service that uses sub-zero temperatures to deeply hydrate and repair the hair, increasing shine by up to 264% in one instant treatment.

Unlike traditional smoothing treatments, Hair.TOXX works by contracting the hair cuticle to seal nutrient-rich ingredients deep within the hair fibre. The result is a flexible, breathable cuticle film that helps reduce frizz, improve humidity resistance, boost shine, increase smoothness and enhance curl definition without flattening the hair's natural texture.

The treatment deeply hydrates and strengthens the hair while creating a smooth, glossy finish and long-lasting manageability. Because it repairs without changing the hair's structure, it is particularly beneficial for clients wanting smoother hair while maintaining curls, waves and movement.
Katie Collins explains: "Cryotherapy helps restore and nourish the hair using natural ingredients and below freezing temperatures. These ingredients are specifically formulated to help hydrate and strengthen your hair and work alongside the Cryotherapy machine which contracts the cuticle, sealing it and leaving it sleek and shiny, whilst also locking the treatment deep within the hair for long lasting results and internal repair.

"This treatment is perfect for anyone who is struggling with hair feeling dry and dull or anyone looking to improve the overall condition and manageability of their hair."

This innovative treatment won Best Salon Treatment at the Woman & Home Hair Awards and the shampoo you take home won best Shampoo for Shine at the Marie Claire Hair Awards!

Keratin Blow Dry in London: Smooth, Sleek and Manageable Hair

For clients looking for maximum smoothness and easier day-to-day styling, a keratin blow dry treatment remains one of the most popular anti-frizz treatments at Haug London Haus.

This long-lasting smoothing treatment helps reduce fluffiness, minimise tangles and create a sleeker cuticle, making hair easier and quicker to style every day. It is particularly effective for thick, unruly or dehydrated hair that struggles in humid weather.

Dan explains: "It's particularly good for people with frizzy, fluffy and dehydrated looking hair. It decreases frizz and increases manageability, making styling quicker and easier whilst also reducing tangling. The smoother cuticle results in a radiant, luxe shine, giving the appearance of instantly healthier hair."

Golden Hour Hair Rescue: The Summer Hair and Scalp Reset

Many people focus on the hair itself when tackling frizz, but scalp health can have a significant impact on the condition and appearance of the hair.

Summer sun, heat, sweat and UV exposure can leave the scalp feeling tight, sensitive and dehydrated, affecting overall hair health and contributing to dryness and roughness.

The Golden Hour Hair Rescue Treatment at Haug London Haus is designed specifically to combat the effects of summer. The treatment begins with a soothing Scalp Clinix treatment enriched with Biotic Technology, fermented ingredients and Edelweiss extract to help support the scalp microbiome and calm irritation. The treatment comforts tight, sun-stressed scalps, replenishes lost moisture and helps restore balance after prolonged exposure to heat and UV rays.

This is followed by a Fibre Clinix Instant Infusion Concentrate treatment that restores structure, improves elasticity, boosts shine and strengthens the hair, leaving it smoother, softer and significantly more manageable.

"Golden Hour Hair Rescue is the ultimate summer reset," says Siobhan. "It deeply comforts dry, sun-stressed scalps while strengthening and restoring shine to damaged hair, leaving both feeling refreshed, healthy and beautifully revived."

Hair Rehab with Fibre Clinix: Repair Damaged Hair and Reduce Frizz

When frizz is caused by damage, breakage or over-processing, strengthening the hair from within is often the most effective solution.

The Hair Rehab Treatment begins with a Molecular Hair Scan, which analyses the hair at a microscopic level. Think of it as like an X-ray for hair, this advanced technology allows our hair specialists to see inside the cortex and assess damage, colour health and overall condition before prescribing a bespoke treatment plan.

The service includes a Scalp Scrub to remove build-up and dead skin cells before the Fibre Clinix Instant Infusion Concentrate treatment powered by Bondfinity Technology works to rebuild broken bonds within the hair, restoring strength, moisture and elasticity.

The result is healthier, stronger hair that is less prone to frizz, breakage and rough texture.

Philipp Haug explains: "Fibre Clinix is an intensive strengthening treatment powered by Bondfinity Technology, helping to rebuild broken bonds within the hair, restoring strength, resilience and a healthier-looking finish. It's the ideal pairing with a haircut or colour appointment."

How to Reduce Frizzy Hair Between Salon Visits

Professional salon treatments can make a dramatic difference, but your home haircare routine matters too.

Siobhan recommends drying hair gently with a microfibre towel rather than rubbing it aggressively. This helps protect the cuticle layer and reduces unnecessary roughness.

"Drying with a microfibre towel is ideal as this doesn't damage the cuticle layer. Pat dry rather than rough drying or rubbing the hair. Use an anti-humidity product to smooth down the cuticle layer and protect hair from taking on excess moisture."

She also recommends embracing natural texture rather than fighting it.

"Braids are a beautiful way to turn frizz into beach waves. Smooth a light oil over the surface of the hair with the palms of your hands, create a braid and secure the ends with a silk elastic. Take it out at the end of the day for tousled beach waves with no frizz."
