Duration for Leaving in Semi-Permanent Hair Dye
To determine how long you should leave the color in your hair when using semi-permanent dye, consider your hair’s porosity and the desired intensity of the shade. Generally, it is recommended to leave it on for 20-30 minutes. However, if you want a more intense result that will last longer, opt to leave it on for 40 minutes or even up to an hour.

To prevent fading and maintain results between coloring sessions, choose gentle shampooing products that are free from sulfates. Additionally, use heat protectants when styling with hot tools such as blow dryers or curling wands/irons.

Hair Porosity Leaving Duration
Low Porous 20 min – 30 min Intense Color & Long Lasting Result

Bleaching Over Permanent Dye

Bleaching Over Permanent Dye
Before making drastic changes, you must first bleach your hair if it was treated with permanent dye. This process is crucial to prepare your hair for semi-permanent color and ensure the best results.

Here are some key considerations for bleaching over permanent dye:

  1. Expert Consultation: Always consult with a hair specialist before attempting to bleach your hair, especially if it has been previously treated with permanent dye. They can assess your hair’s condition and provide personalized advice.

  2. Recovery Period: Patience is key. Wait at least 2-4 weeks after your last permanent dye application before bleaching. Rushing this process can risk hair damage and disintegration.

  3. Undertone Management: Be prepared for potential undertone issues. Permanent dye layers may have red undertones, so plan your semi-permanent color accordingly.

  4. Clarifying Shampoo: If your hair turns out overly dark after bleaching, a clarifying shampoo can help lighten it slightly. It’s a handy tool for correcting color mishaps.

  5. Henna Blend: If you’re dealing with henna-treated hair, consider henna blends that coat the hair without affecting its bonds. They can help you achieve the desired color without compromising your hair’s integrity.

Bleaching over permanent dye requires careful planning and consideration of these factors. Taking the time to do it right will yield the best results while minimizing damage to your precious locks.
