* Current color and condition: If your hair is already damaged or very dark, bleaching it can cause breakage, dryness, or an undesirable color.
* Desired level of lightness: Going for a drastic change (like dark brown to platinum blonde) in one session is risky and likely to damage short hair.
* Bleach volume and timing: Using a higher volume developer or leaving the bleach on too long can lead to over-processing and breakage.
* Hair texture: Fine or thin hair is more susceptible to damage from bleaching than thick or coarse hair.
Here's a general idea of what to expect:
* Lifting Color: Bleach will lighten your hair, removing pigment. Short hair often lifts faster due to being closer to the scalp's heat.
* Damage: Bleaching always causes some damage. Short hair might be able to withstand more than longer hair, but it's still crucial to be cautious.
* Color Result: The final color depends on your starting color and how long you bleach. You'll likely go through stages of orange or yellow before reaching a lighter blonde.
* Potential Problems: Over-processing can lead to breakage, especially if the hair is already damaged or the bleach is too strong.
Recommendations
* Do a strand test. Before bleaching your entire head, test a small, hidden section of your hair to see how it reacts to the bleach.
* Start with a low-volume developer. A lower volume developer will be less damaging.
* Don't leave the bleach on too long. Check your hair frequently.
* Moisturize Deep conditioning treatments are essential for maintaining healthy, bleached hair.
When to see a professional: If you have a complicated color, are aiming for a drastic change, or are concerned about damaging your hair, it's always best to consult a professional hairstylist. They can assess your hair's condition, formulate the right bleach mixture, and minimize damage.
