Keratin Smoothing vs Brazilian Blowout | What's the Difference? | Fergal Doyle Hair Bristol

Keratin smoothing treatments and Brazilian blowouts are two of the most popular frizz-fighting hair services available — but they're not the same thing. If you're considering a smoothing treatment at Fergal Doyle Hair in Bristol, here's everything you need to know about the key differences between the two so you can choose what's right for your hair.

What Is a Keratin Smoothing Treatment?

A keratin smoothing treatment infuses the hair with a keratin-based formula that fills gaps in the hair's outer cuticle layer, creating a smooth, sealed surface. It dramatically reduces frizz, increases shine and makes the hair significantly more manageable. Most keratin treatments require you to keep hair dry and straight for 48 to 72 hours after the appointment. Results typically last 3 to 5 months.

What Is a Brazilian Blowout?

A Brazilian blowout is a type of smoothing treatment that uses a liquid keratin formula to create a protective protein layer around the hair shaft. Unlike traditional keratin treatments, most Brazilian blowout formulas allow you to wash and style your hair immediately after the service. Results are typically slightly less long-lasting than a full keratin treatment — usually 8 to 12 weeks — but the convenience factor is significant.

Key Differences at a Glance

Keratin treatments generally offer stronger, longer-lasting smoothing results (3 to 5 months) but require 48 to 72 hours of care after the appointment. Brazilian blowouts are more flexible post-treatment and deliver a more natural result — reducing frizz while preserving some of the hair's natural movement and wave. Neither treatment is permanent, and both require sulphate-free shampoo to maintain results.

Which Is Right for Your Hair?

If your hair is very frizzy, coarse or thick and you want the maximum smoothing effect for the longest possible time, a keratin treatment is likely the better choice. If you want to reduce frizz while keeping some natural texture, or if you need to be able to wash your hair sooner after the appointment, a Brazilian blowout may suit you better. The best way to decide is to book a consultation — our experts will assess your hair and recommend the right option.
