Setting up the Extensions & Bleach

To get rid of imperfections or any product buildup on the extensions, wash them from 2 to 3 times before starting.

Ensure they’re totally dry and put them on single sheets of tin foil.

2. Buy a bleach pack

You can get this from large box stores, for instance, Kmart, Target, or Walmart. They’re usually accessible at a cosmetology or grocery stores. Ensure the pack you are utilizing incorporates developer, gloves, and bleach.

  • Try to get a pack with clear guidelines. The more clear, the better, since there’s a small chance for blunder! 
  • The darker the extension hair, the more lightening powers you need from your kit. For dark extensions, you’ll go for a kit that incorporates a 40 volume developer since it can offer adequate lift needed.

3. Mix liquid developer & power bleach

Ideally, you do this on a container or glass bowl that is mainly meant for hair color. Precisely, follow the guidelines on the box, since you must put the right ratio. The specific proportion of developer to bleach will change by brand. You should thus check the guidelines before you start working.

3. Fold foil over extensions

This ensures the bleach doesn’t spill out. Bleach ideally works when it’s moist and warm. In this condition, the foil retains heat and keeps the bleach from drying during the process.

4. Check on the extensions

Assess your extensions after every 10 minutes. Strip back the foil and take a gander at the shade of the extensions. When they’re ready for the wash, there’ll be a light yellow shade. If they haven’t accomplished yellow shading in 60 minutes, expel them from the foil to avoid causing any significant harm from excessive processing.

If you utilized a higher volume developer, your extensions must bleach more rapidly as compared to using a lower volume developer.

Managing Extensions Color

1. Wash the extensions

Wash your extensions with a pH balancing shampoo, which will neutralize the hair chemicals and stop processing. Ensure you utilize a deep conditioning treatment. Alternatively, use coconut or olive oil and dessert it on the strands during night time.

  • Some neutralizing shampoos will change shading when applied. Try not to stress, but it’s a sign that the cleanser is working!

2. Drying Extensions

Permit your extensions to dry completely. Check the shading. If you’re not satisfied with it, bleach the extensions once more, but ensure you assess at regular intervals to avoid over-processing.

  • Be incredibly cautious when bleaching twice as lower quality extensions can fall off or break.
