40 Developer Bleach: A Closer Look
Strength and Lifting Power
40 developer bleach, also known as 40 volume developer, contains a higher concentration of hydrogen peroxide, making it the most powerful developer available. This allows it to lift natural hair color by up to seven levels, revealing lighter tones underneath. It's often the go-to choice for achieving a dramatic color change, such as transitioning from dark brown to platinum blonde.
Risks and Precautions
The high concentration of hydrogen peroxide in 40 developer bleach makes it a powerful lightening agent, but it also carries the risk of significant damage. If not used correctly, it can cause hair breakage, dryness, and even scalp irritation. Here's a breakdown of potential risks and mitigations:
Hair Damage and Breakage
- Cause: Excessive exposure to 40 developer bleach can weaken the hair shaft, leading to breakage and split ends.
- Mitigation: Use only on healthy, strong hair. Apply it strategically, focusing on the areas needing lightening. Always use a deep conditioner and hair masks after bleaching to strengthen and hydrate hair.
Scalp Irritation and Sensitivity
- Cause: 40 developer bleach can irritate the scalp, especially for those with sensitive skin.
- Mitigation: Perform a strand test before full application to assess potential reactions. Apply a barrier cream around the hairline to protect the skin. If any discomfort occurs, discontinue use and consult a professional stylist.
