What bleach does
Bleach (hydrogen peroxide + ammonia + persulfates):
- Opens the cuticle aggressively
- Dissolves melanin (and, collaterally, other pigments)
- Breaks disulfide bonds — the strongest bonds in hair
- Creates permanent porosity
- Reduces tensile strength by 25–40%
No conditioning product fully reverses this. Bleached hair is always more fragile than virgin hair.
Rule zero: prevent further damage
- No heat above 150°C (300°F) — ever
- No chlorine or salt water without protection
- No fresh bleach over bleach without 6+ weeks between sessions
- No fresh color over bleach without bond-builders
The recovery routine
Wash day
- Purple shampoo 1x per week (neutralizes brass)
- Sulfate-free clear shampoo 1–2x per week
- Always follow with bond-building or moisturizing mask (5–10 min)
Between washes
- Leave-in conditioner daily on mid-length + ends
- Light oil on ends (argan, sebum.">squalane) nightly
- Silk pillowcase
Weekly deep treatments
Alternate:
- Week 1: Olaplex No.3, K18.">Bond-builder (Olaplex No.3, K18 mask, Redken Acidic Bonding) on wet hair, 10 min
- Week 2: Protein mask (hydrolyzed keratin/wheat)
- Week 3: Deep moisture mask (shea butter, panthenol)
- Repeat
Monthly
- Trim splits — bleach encourages them
- Check in with stylist on scalp and strand health
Ingredients to look for
Repair:
- Hydrolyzed keratin, silk, quinoa proteins
- Amino acids (arginine, glycine)
- Bond-builders (hybrid esters, proprietary peptides)
- Ceramides
Moisture:
- Shea butter
- Panthenol
- Hyaluronic acid (yes, in hair products)
Seal:
- Argan oil
- Squalane
- Jojoba oil
- Light silicones (Dimethicone copolyol — water-soluble)
Ingredients to avoid
- Sulfates daily
- Alcohol denat. high in INCI of leave-ins
- Clarifying shampoos more than once a month
- Heavy silicones at roots
Purple/blue shampoo — how to use
To neutralize brass/orange tones:
- Apply to dry or wet hair
- Leave 3–5 minutes (longer if very brassy)
- Don't use more than 1x per week — it can dry hair
- Follow with conditioner
The real timeline
Realistic expectation: with perfect care, bleached hair feels healthier in 8–12 weeks. It won't feel virgin again until you grow it out and cut off the bleached length — usually 12–18+ months.
Going back to natural
If you want to grow out and reclaim health:
- Color matcher (dye roots to match length) — less harsh than another bleach
- Color-correct to medium tone
- Grow 4–6 inches, trim damage progressively
- Or "the big chop" — cut most damage at once
Scalp care
Bleach irritates scalp too. Use a gentle shampoo and consider scalp serums with panthenol and niacinamide to restore the barrier.
What Mutaly adjusts for bleached hair
Mutaly's quiz flags bleach as high-damage input and shifts recommendations toward bond-builders, rich moisturizers, and low-protein daily care.
