Why It's a Bad Idea:
* Improper Activation: Bleach powder *requires* a developer (usually hydrogen peroxide) to activate and lift color from your hair. Without it, the bleach won't work correctly, if at all.
* Unpredictable Results: Even if you try to substitute another developer, Splat's formula is designed to work with their specific Splat-Oxide strength. Using a different developer could lead to uneven lifting, hot roots, over-processing, or under-processing.
* Hair Damage: Without the proper developer, you run a high risk of extreme hair damage, breakage, and even chemical burns to your scalp.
If You Absolutely Must Use the Bleach (Though I Strongly Advise Against It):
I highly recommend buying a new kit or using a different bleach product. However, if you are in a dire situation:
1. *Research is Crucial:* If you absolutely must try, you would need to thoroughly research hydrogen peroxide developers. Different developers have different strengths (volumes - e.g., 10 vol, 20 vol, 30 vol, 40 vol). Splat-Oxide's volume is not specified, but it's likely a 20 or 30 volume.
2. *Strand Test:* Perform an absolute STRAND TEST. Mix a very small amount of the bleach with the substitute developer and apply it to a hidden strand of your hair (e.g., underneath, near the nape of your neck). Observe the results and how your hair reacts.
3. *Go Low and Slow:* If you proceed, use the lowest volume developer (e.g., 10 vol or 20 vol) for the shortest possible processing time.
4. *Baby Your Hair:* Deep condition your hair afterwards, whether the results are what you hoped for or not.
Alternatives:
* Purchase a New Splat Kit: This is the safest and most reliable option.
* Use a Different Bleach Kit: There are many other bleach kits available at drugstores and beauty supply stores. Choose one that includes the developer and has good reviews.
* Go to a Professional: A professional hairstylist can assess your hair's condition and use the correct products and techniques to lighten your hair safely and effectively.
In conclusion, avoid using Splat Hair Lightening Bleach without the Splat-Oxide. It's simply not worth the risk of damaging your hair. Choose a safer alternative or consult a professional.
