Bleaching your hair shouldn’t feel like torture. Yet every year, thousands of people experience painful scalp burns from bleach – some severe enough to require medical attention.
Whether you’re a salon regular or attempted a DIY bleach job, this guide will walk you through exactly how to treat burns, when to worry, and how to prevent future damage. We’ve consulted dermatologists and professional colorists to bring you the most reliable information.
Understanding Bleach Burns: More Than Just Discomfort
The Science Behind the Burn
Bleach doesn’t just lighten your hair – it creates a chemical reaction on your scalp:
- pH Disruption
- Healthy scalp pH: 4.5-5.5 (slightly acidic)
- Bleach pH: 9-11 (highly alkaline)
- This imbalance breaks down your skin’s protective barrier
- Oxidation Reaction
- The lightening process generates heat
- Can reach up to 110°F (43°C) on your scalp
- More concentrated formulas create more intense reactions
- Moisture Stripping
- Removes natural oils (sebum)
- Leaves skin vulnerable to cracking and infection
Degrees of Scalp Burns
| Severity | Symptoms | Healing Time | Action Needed |
|---|---|---|---|
| Mild | Slight redness, tingling | 1-3 days | Home treatment |
| Moderate | Painful burning, swelling | 1-2 weeks | Medical consultation |
| Severe | Blisters, weeping, fever | Weeks-months | Emergency care |
Real Case Study:
“My client came in with second-degree burns after leaving bleach on for 90 minutes. We had to stop the service and send her straight to urgent care.” – Jessica L., Master Colorist
Emergency Response: What to Do RIGHT NOW
Step-by-Step First Aid
- Rinse Immediately

- Neutralize the Burn
- Mix 1 tbsp baking soda with 2 cups water as a neutralizing rinse
- Pat (don’t wipe) dry with clean paper towels
- Pain Management
- Take ibuprofen (reduces inflammation)
- Apply 1% hydrocortisone cream (max 2x daily)
- Use fragrance-free aloe vera gel
When to Go to the ER:
- Difficulty breathing (allergic reaction)
- Burns covering more than 3″ diameter
- Pus or foul-smelling discharge
