Inoar Hair Products South Africa: Keratin Treatments and Frizzy Hair Care

TL;DR:

• Inoar is a Brazilian professional hair care brand known for keratin treatments and aftercare — stocked and used by Partners Hair
• The Brazilian keratin treatment smooths frizz for up to 4 months. The aftercare range maintains those results at home
• Sulphate-free aftercare is essential after any keratin treatment — regular shampoo strips the treatment prematurely
• South Africa's humidity makes keratin treatments particularly popular in Cape Town
• The Inoar Japanese Silk Mask is a standout product — deeply nourishing for dry, frizzy and over-processed hair

Brazil and South Africa have one hair concern in common: humidity. Cape Town's coastal humidity is one of the main reasons keratin treatments have become so popular here, and Inoar — a Brazilian professional hair care brand — was built around exactly that challenge. Here's what Partners Hair stylists think of the range and how to get the most from it.

01 — What Inoar Is

Inoar is a Brazilian professional hair care brand that built its reputation on keratin-based treatments and aftercare. Their Brazilian keratin treatment is one of the most well-known smoothing services used in salons, combining keratin with heat to temporarily relax frizz and leave hair smooth for months. The aftercare range — shampoos, conditioners, masks, and leave-ins — is formulated to extend and maintain those results at home.

"Inoar products are specifically formulated to work with keratin-treated hair," says Lewis. "The aftercare range is sulphate-free, which is essential after any keratin treatment. Using sulphate shampoos after a keratin service strips the treatment within weeks. Inoar aftercare keeps the results lasting closer to the full four months."

02 — The Brazilian Keratin Treatment

The Inoar Brazilian keratin treatment is a salon service that smooths the hair's cuticle using keratin protein and heat. It reduces frizz significantly, makes the hair more manageable, adds shine, and can last three to four months depending on hair type, aftercare routine, and how often you wash.

"Cape Town's humidity makes this one of the most in-demand services we offer," says Debbie at the Waterfront. "Clients who struggle with frizz year-round — particularly those with thick, wavy or naturally frizzy hair — see a dramatic difference. The first wash after a treatment is always the moment clients really feel the change."

Important: wait 72 hours before washing after a keratin treatment. Avoid tying the hair back, wearing hats, or anything that could crease it during those first three days while the treatment fully sets.

03 — The Inoar Japanese Silk Aftercare Mask

The standout product in the Inoar range for home use is the Japanese Silk Mask — a deeply nourishing treatment that maintains the softness and shine from a keratin service, and works equally well as a general intensive treatment for dry, frizzy or over-processed hair. Applied after shampooing, left on for five to fifteen minutes, and rinsed well.

"This mask is one I recommend even for clients who haven't had a keratin treatment," says Judy, head trainer. "It's a genuinely excellent moisture mask for any hair type that's dry or frizzy. The texture is rich but rinses cleanly — no heaviness or buildup. Clients who use it weekly consistently see softer, more manageable hair."

The Japanese Silk Mask is the at-home companion to the salon-only Inoar Japanese Silk Treatment — a separate professional smoothing service that delivers more intense, longer-lasting results than the home mask alone.

04 — The Wider Inoar Range

Beyond the Japanese Silk line, the Inoar collection at Partners Hair covers several core ranges, each formulated for a different concern:

• G.Hair Keratin — the original Brazilian keratin smoothing system, the line that built Inoar's global reputation
• Argan Oil — daily-use shampoo, conditioner and treatment enriched with Moroccan argan oil for shine, softness and frizz control
• Afro Vegan — a dedicated range for Type 4 natural, coily and chemically processed hair, with vegan formulas focused on deep conditioning and curl definition
• My Curl My Crush — hydration and definition for waves, curls and coils, sulphate-free and silicone-free, Curly Girl Method approved
• Absolut Speed Blond — toning and brightening care for blonde, highlighted and lightened hair
• Daymoist — hydration-focused daily care for dry hair that needs lightweight, everyday moisture

05 — The Sulphate-Free Aftercare Foundation

The Inoar shampoo and conditioner range is sulphate-free — which makes it appropriate both for maintaining keratin treatments and for regular use on dry, colour-treated, or frizzy hair. Sulphate-free formulas cleanse without stripping the cuticle's natural oils or disrupting keratin bonds.

"The rule after any keratin treatment is sulphate-free shampoo, indefinitely," says Charlene at Canal Walk. "Inoar aftercare is designed for this. But you can also use it as a standard sulphate-free routine for frizzy hair even without a treatment history — the products are formulated for frizz-prone hair regardless."

06 — Daily Maintenance for Frizzy Hair

For day-to-day frizz management between washes, a light leave-in conditioner on damp hair before styling creates a humidity barrier that reduces how much frizz returns throughout the day. Pair it with a finishing oil or serum on dry hair to seal the cuticle and add shine. In Cape Town's climate, this two-step approach — leave-in on damp hair, serum on dry hair — gives significantly better frizz control than either alone.

07 — Who Benefits Most From Inoar

The Inoar range is most effective for: clients who have had or are maintaining a keratin treatment — naturally frizzy, wavy, or coarse hair types — colour-treated hair that's also frizz-prone — clients in Cape Town and coastal areas where humidity is a persistent challenge. It's less suited to very fine, straight hair that doesn't have a frizz concern.

Frequently Asked Questions

How long does the Inoar Brazilian keratin treatment last?

Three to four months with proper aftercare — sulphate-free shampoo, limited washing frequency, and avoiding chlorine and salt water where possible. Clients who wash daily with sulphate shampoo will see results fade significantly faster.

Can I use Inoar products without having had a keratin treatment?

Yes — the aftercare range is formulated for frizzy and dry hair and works well as a standalone sulphate-free routine. The Japanese Silk Mask in particular is an excellent weekly treatment for any dry or frizzy hair type.

What is the difference between the Inoar Japanese Silk Mask and Japanese Silk Treatment?

The Japanese Silk Mask is a take-home weekly conditioning treatment you apply after shampooing. The Japanese Silk Treatment is a salon-only smoothing service performed by a stylist using heat and professional-grade formulas — longer lasting and more intensive.

How long do I wait before washing after a keratin treatment?

72 hours minimum. During this time, avoid anything that creases or bends the hair — no ponytails, headbands, sunglasses on the head, or hats. The treatment needs time to fully bond.

Is Inoar suitable for colour-treated hair?

Yes — the sulphate-free formulas are colour-safe and won't accelerate fade. Keratin treatments can be done on colour-treated hair, though timing relative to colouring services should be discussed with your stylist.
