Bleaching

What does bleaching actually do?

Bleaching removes your hair's natural pigment to make way for lighter shades. The darker your starting point, the more stages of lightening your hair goes through — your stylist monitors each stage to reach your target shade safely.

Where you stop on that scale depends on your target colour. Going to a warm caramel brown may only require lifting 2–3 levels. Reaching platinum blonde on dark Asian hair typically requires lifting 7–8 levels, often across multiple sessions.

Unlike single-tone colour which deposits pigment, bleaching removes it. That's why it's more demanding on the hair and requires careful technique — you can't simply add more time or stronger product without consequences.

Bleaching Asian hair: why it's different

Asian hair is thicker and darker than most hair types, which makes bleaching more involved. Here's what that means in practice.

• More pigment — Dark hair has more pigment, so it takes more sessions to lighten safely. Going platinum from black requires multiple sessions — pushing too far in one sitting risks damage.
• Thicker hair — Asian hair strands are denser, so the bleach needs more time to work through evenly. This is why precise timing matters.
• Warm undertones — As Asian hair is bleached, it passes through orange and yellow-orange stages before reaching pale yellow. These warm undertones are natural and expected — they need to be neutralised with a toner, not masked with more bleach.
• Damage risk — Over-bleached hair gets dry and breaks easily. Our Korean bleach hair specialists monitor your hair during processing and stop before that point.

How we bleach at Miin

When you bleach hair at our Orchard salon, we prioritise hair health alongside achieving your colour goal. We'd rather take two well-controlled sessions than rush a single damaging one.

• Thorough consultation — Your stylist assesses your hair's current condition, colour history, and elasticity before recommending a plan. If your hair has been previously coloured or chemically treated, the approach will differ from virgin hair.
• Gentler products, better results — We choose the gentlest effective product for your hair type and apply a scalp protector before processing. A milder formula with longer processing time gives more even, less damaging lift than aggressive alternatives.
• Sectioned application — Bleach is applied in precise sections, working from mid-lengths and ends before roots (which process faster due to scalp heat). This prevents hot roots and uneven lift.
• Progress checks — Your stylist checks the hair at regular intervals during processing, monitoring both lift level and hair condition. Processing stops when the target lift is reached — not when a timer goes off.
• Post-bleach treatment — Every bleaching session includes a treatment to restore strength and lock in moisture. Upgrade to Olaplex for the strongest repair. This isn't optional — it's built into the service.

Single session vs multiple sessions

How many sessions you need depends on where you're starting and where you want to end up.

• Single session (1 bleach + toner) — Suitable for lifting 2–4 levels. Can achieve warm blonde, caramel, or light brown from virgin dark hair. Also appropriate for pre-lightening before fashion colours (e.g. rose gold, dusty pink).
• Double session (2 bleaches + toner) — Required for lifting 5–7+ levels. Necessary for platinum, silver, or very light ash blonde from dark Asian hair. Sessions are spaced 2–4 weeks apart to let the hair recover between treatments.

Why toner matters after bleaching

Bleach lifts colour out but doesn't put the right colour in. After lightening, your hair sits at a warm base — typically orange or yellow. A toner corrects that warmth to achieve your actual target shade.

For example, if you want ash blonde, your stylist lifts the hair to pale yellow, then applies an ash or violet-based toner to cancel the yellow and land on a cool, clean blonde. Without toner, bleached hair looks brassy and unfinished.

Toner is a separate step with its own processing time. At Miin, we list it as a separate service so pricing is transparent — see our services page for toner pricing.

Bleaching vs colour: which do you need?

Not every colour change requires bleach. Here's a quick guide.

• Going darker or same level — Single-tone colour only. No bleach needed.
• Going 1–2 shades lighter — High-lift colour can sometimes achieve this without bleach, depending on your hair's condition. Your stylist will assess.
• Going 3+ shades lighter — Bleaching is required. The greater the lift, the more sessions may be needed.
• Fashion colours (pink, blue, silver, etc.) — Almost always require bleaching first to create a light enough base for the colour to show true.
• Dimensional lightening (highlights, balayage) — Uses bleach but only on selected sections. See highlights, half highlights, or balayage.

Aftercare for bleached hair

Bleached hair requires more care than natural or colour-treated hair. Bleached hair is more fragile and vulnerable to damage, dryness, and colour fade.

• Wait 48–72 hours before washing after bleaching — this lets the cuticle settle
• Use sulphate-free shampoo — sulphates strip moisture and accelerate tone fade
• Use a purple or silver shampoo 1–2 times per week to counteract brassiness on blonde hair
• Apply a leave-in conditioner or hair oil daily — bleached hair loses moisture faster
• Minimise heat styling; always use heat protectant when you do
• Avoid chlorine and prolonged sun exposure — both cause rapid tone shift and dryness
• Book a Miin Express treatment or Miin Signature treatment every 3–4 weeks to rebuild protein and maintain elasticity
