Bleaching is a chemical process that opens the cuticle layer and removes pigments from inside the hair shaft — in doing so, it also breaks the disulfide bonds that give hair its strength and elasticity. Without proper protection, every bleaching treatment leaves the hair fiber weakened, porous and dehydrated. This is exactly why preparation is just as important for beginners as the bleaching itself — because breakage, dryness and a “chewing-gum” feel can be avoided from the start with the right system.
4 Weeks Before: The Right Preparation
A successful first bleach doesn’t start on application day — it begins two to four weeks earlier with intensive care. Well-hydrated hair handles the bleaching process significantly better and is less prone to damage.
- Add moisturizing masks and deep-conditioning treatments to your weekly routine
- Avoid heat styling, flat irons and harsh styling products during this phase
- Skip washing your hair right before the appointment – natural scalp oils protect the skin from irritation
- Always perform a strand test on a hidden section to check how your hair reacts
During Bleaching: Protecting Your Hair on a Molecular Level
For beginners, this is the most critical moment: bleach should never hit unprotected hair “raw”. The patented pH Plex system is the first and only professional plex system developed specifically for at-home use. pH Plex No. 1 protect is mixed directly into the bleach — never applied on its own — and shields the hair during the development time without altering the formula or processing time.
The system works because it bonds to all 21 amino acids of the hair’s protein structure and builds a stabilizing network inside the cortex — a kind of “zipper effect” from within. At the same time it controls the pH value: Step 1 sits at around pH 9.0 (aligned with the bleach), while Step 2 brings the hair back into its natural acidic range at pH 5.0.
Right After Rinsing: Repair Before You Shampoo
This is where many beginners make their first mistake: reaching straight for the shampoo. The correct approach: rinse the bleach thoroughly until the water runs clear — but don’t shampoo yet. Now apply pH Plex No. 2 repair and let it work for 5–10 minutes to stabilize the hair structure in this highly sensitive state.
The First Weeks After Bleaching: A Beginner Care Routine
Bleached hair loses moisture faster and needs an adjusted care routine. These habits should become your new standard from day one:
- Wash less frequently – every 3 to 4 days is plenty
- Use a gentle, sulfate-free shampoo formulated for colored or bleached hair
- Apply a conditioner after every wash
- Use pH Plex No. 3 stabilize weekly as an intensive at-home treatment
- Always apply heat protection before blow-drying, straightening or curling
- Don’t forget UV protection – even outside the summer months
The Most Common Beginner Mistakes – and How to Avoid Them
| Mistake | Better approach |
|---|---|
| Bleaching over already bleached hair | Only bleach the regrowth to prevent breakage |
| Leaving bleach on longer for a lighter result | Lift gradually over several sessions on dark hair |
| Bleaching right after a perm | Wait at least 2 weeks between chemical treatments |
| Blow-drying hot without heat protection | Reduce heat styling and always use a heat protectant |
| Using drugstore care after bleaching | Choose professional bond builders and sulfate-free systems |
Checklist: Your Kit for the First Bleach
As a beginner, you’ll need the following for a safe result:
- A high-quality bleach powder/cream + developer (matched to your starting level)
- pH Plex No. 1 protect (to mix into the bleach)
- pH Plex No. 2 repair (directly after rinsing)
- pH Plex No. 3 stabilize (weekly at-home treatment)
- Sulfate-free shampoo and conditioner for color-treated hair
- Optional: purple shampoo to neutralize yellow tones
