Should I Use 20 or 30 Developer with Bleach?
Deciding on the right developer strength for bleach can feel daunting, especially for beginners. The question of whether to use 20 or 30 developer is common, and the answer depends on a few key factors:
1. Your Hair Type and Desired Level of Lift:
- Fine, light hair: 20 developer might be sufficient for subtle lightening.
- Thick, dark hair: 30 developer is typically needed for significant lightening.
- Previously colored hair: The developer strength needed will depend on the existing color and desired outcome.
2. Your Experience Level:
- Beginner: Opt for 20 developer, which offers more control and a lower risk of damage.
- Experienced: You may be comfortable using 30 developer, but remember that it lifts hair faster and can be harsher.
3. Your Desired Result:
- Slight lift: 20 developer is ideal for subtle highlights or a few shades of lightening.
- Dramatic change: 30 developer is necessary for a significant color lift.
Here's a breakdown of developer strengths:
- 10 Volume (3%): Used for toning, subtle highlights, or darkening hair.
- 20 Volume (6%): Provides medium lift, suitable for lifting a few shades or highlighting.
- 30 Volume (9%): Offers high lift, suitable for dramatic color changes, but may be harsh on fine or damaged hair.
- 40 Volume (12%): Provides maximum lift, often used for high-lift blondes, but requires careful application and can be damaging.
Important Considerations:
- Patch Test: Always perform a patch test before using bleach to ensure you don't have an allergic reaction.
- Damage: Both 20 and 30 developer can damage hair, especially if used improperly or too frequently.
- Professional Help: If you're unsure about the best developer strength, it's always best to consult with a professional stylist.
Ultimately, the decision of whether to use 20 or 30 developer comes down to your specific hair type, experience level, and desired outcome. Consider all of these factors before deciding to achieve your desired results without risking damage.
