@hairdracademy: What peroxide actually does Peroxide is used in hair coloring to: • Open the hair cuticle (outer layer of hair) • Remove natural pigment (melanin) • Activate hair dye so new color can go inside the hair shaft Higher percentage = stronger lift (lightening power) ⸻ 📊 Levels explained (1.9% → 9%) 🔹 1.9% (very low strength) • Very gentle • Used for: • Toning (e.g. removing yellow tones in blonde hair) • Slight color deposit (no real lightening) • Minimal damage 👉 Think: refreshing color, not changing it ⸻ 🔹 3% (10 volume) • Low strength • Used for: • Darkening hair • Covering grey hair • Slight lift (about 1 level) • Safe for regular coloring Great for lifting low and slow for bleach to create a cleaner lift 👉 Think: basic coloring ⸻ 🔹 6% (20 volume) • Medium strength • Used for: • Lightening hair by 1–2 levels • Standard permanent dye • Grey coverage 👉 Think: most common salon strength ⸻ 🔹 9% (30 volume) • Strong • Used for: • Lightening 2–3 levels • Stronger blonding • More damage risk if misused 👉 Think: noticeable color change ⸻ ⚠️ Why different strengths exist Hair varies a lot: • Fine vs thick • Dark vs light • Virgin vs previously dyed So you need different peroxide strengths to: • Control how much you lighten • Avoid unnecessary damage • Achieve the exact shade you want ⸻ ⚠️ Important safety note • Higher % = more damage + dryness risk • Using 9% incorrectly can lead to: • Breakage • Uneven color • Scalp irritation ⸻ 🧠 Easy way to remember • 1.9% → tone only • 3% → deposit color • 6% → normal lift • 9% → strong lift #proxide #salon #education #colour #freeeducation
