* Uneven Bleaching: Hairspray can create a barrier on the hair shaft, preventing the bleach from penetrating evenly. This can lead to splotchy, uneven, or patchy results.
* Chemical Reactions: The chemicals in hairspray (like polymers and resins) might react negatively with the chemicals in bleach (usually hydrogen peroxide and ammonia or an alternative alkali). This could damage your hair more severely than bleaching alone.
* Heat and Damage: Bleach already puts stress on your hair. Hairspray buildup can trap heat during the bleaching process, potentially causing more breakage, dryness, and overall damage.
* Reduced Effectiveness: Hairspray buildup can weaken the effect of the bleach and you may end up having to apply it multiple times, increasing the damage.
How to Wash Hairspray Out:
1. Use a Clarifying Shampoo: A clarifying shampoo is designed to remove buildup from products like hairspray.
2. Lather Thoroughly: Make sure to work the shampoo into your scalp and all the way down the lengths of your hair.
3. Rinse Completely: Rinse until the water runs clear. You might need to shampoo twice to get all the hairspray out.
4. Condition: Follow up with a moisturizing conditioner to replenish any moisture lost during the washing process.
5. Dry Completely: Ensure that your hair is completely dry before you start the bleaching process.
In summary, to protect your hair and get the best results, always wash out any hair products, especially hairspray, before bleaching.
