When you bleach your hair, the real danger is not damaged hair – it is a chemical burn on the scalp. Written for the Hari Raya season, this guide keeps it to three things: swap 12% peroxide for 9% and go through the process in 2 rounds, prime the scalp with half a tube of Labbell Bio Protein before you start, and keep the bleach 5 cm away from the roots so it never touches the scalp. Hold a few extra details before and after, and you still get the lift you want without the burn risk.
Why 9% peroxide instead of 12%?
The short answer: 9% is a lower concentration, so it irritates less, yet doing 2 rounds still gives you a gradual lightening effect.
- Instead of high-concentration 12% peroxide, do 2 rounds with 9% peroxide.
- Why: the lower concentration reduces irritation while still achieving stage-by-stage lightening.
How do you protect the scalp with Labbell Bio Protein?
The short answer: use Labbell Bio Protein as a protective ampoule before the bleaching process starts.
How to apply
- Spread half a tube evenly over the scalp and leave it for 10-15 minutes.
- Wipe off the excess with tissue before applying the bleach.
Can the bleach touch the roots?
The short answer: no. Make sure the bleach does not touch the scalp – keep it 5 cm from the roots.
- Tip: use a fine brush and work on the ends first.
What should you watch during the process?
The short answer: watch the colour of the scalp. If it turns red or bright pink, that is your stop signal.
- Stop immediately and rinse with cold water.
- Note: darker scalp skin is more sensitive – do a 24-hour allergy test beforehand.
Should you wash your hair before bleaching?
The short answer: no. Do not wash your hair for 2 days before bleaching, so the scalp’s natural oil stays as a protective layer.
When must you stop, or check with a professional first?
The short answer: never repeat the process on an irritated scalp, and speak to a professional if you have a history of reactions or are using scalp medication.
- DO NOT repeat the process if the scalp is already irritated.
- Consult a professional if you have had an allergy to hair products before, or are using scalp medication such as corticosteroids.
How do you recover after bleaching?
The short answer: put moisture back and give the hair a rest from heat.
- Use Labbell Bio Protein as an after-procedure treatment to moisturise the hair.
- Avoid heat (hair dryer, straightener) for 1 week.
Summary
Do it in 2 rounds with 9% peroxide, prime the scalp with Labbell Bio Protein, and keep the bleach 5 cm off the roots – with the small details like not washing your hair for 2 days before, you get the lightened hair you want without risking a chemical burn.
