Hair Treatment FAQs
Some of the most popular types of hair treatments include: Keratin – smooths and straightens curly or frizzy hair for up to 3 months. This treatment is also known as the Brazilian Blowout. Scalp – the go-to indulgence for improving itchy, flaky scalps. Hot oil – this salon treatment can transform dry and damaged hair into shiny, silky locks. Moisture – deeply nourishing, a quality moisture treatment can boost the look and health of dry and heat damaged hair. Detox – cleanses your hair from product and other impurities, improving the overall health of your hair and scalp. Some detox hair treatments can even stimulate hair growth. Relaxing – used to reduce and control curl and frizz, the results of relaxing treatments should last until your hair grows out. Toning – these treatments are for dyed hair and can help to neutralise warm or brassy tones, reinvigorate colour vibrancy, and add gloss. Glossing – leaves you with high-shine locks that can last for weeks.
Talk to your stylist. Tell them what your hair goals are, and ask them to advise you on the best types of treatment for you based on your hair’s type, length, and condition.
Some benefits are aesthetic only, but if your hair is dull, dry or damaged it could benefit from a detox or hot oil treatment. Scalp, detox, and moisturising treatments can help improve your hair’s health.
It largely depends on the treatment. You can have keratin treatments up to 3 times a year, relaxing treatments 3-4 times a year, and hair toning once every 6-8 weeks. You can enjoy scalp treatments every 2-4 weeks, detox and hot oil treatments once every 1-2 weeks, and moisturising treatments once a week or more.
What your hair stylist does during a treatment will be dictated by the treatment you choose. Your treatment may be carried out on washed, unwashed, wet, or dry hair. Ask your stylist before you book your appointment what’s involved in the process and how long it’s likely to take. Applying a detox treatment takes a matter of minutes, hair toning can take between 5-20 minutes, hot oil and moisturising treatments take around 20 minutes, glossing is likely to take between 30 and 40 minutes, and you’ll need to allow 1-2 hours if you’re having your hair relaxed, and 1-3 hours if you’re booked in for a keratin treatment.
No. If you have dry, over-processed, or damaged hair you may want to avoid treatments that could make your hair health worse or irritate your scalp. Ask your hair stylist to advise you on the treatments that would work best for you.
