How long can you leave bleach on hair when doing hair colour?
Bleaching does not have to be a one-size-fits all process. It depends on several factors such as hair texture and colour.

Hair Texture and Colour  How Long to Leave it on?
Blonde hair Takes 15 to 20 min
Dark hair Should be done in 30 minutes and advised to be separated into few sessions.
Fine hair Can take 10 to 15 mins; fine hair will process quicker because it has thin cuticle.
Coarse hair Takes 30 minutes; this hair kind is more difficult and may need at most two applications


There are more factors that influence how long bleach remains on your skin.

  • The colour you are aiming to achieve
  • If your hair has ever been coloured before

What does bleach hair do?
Bleach is an aggressive product. It dyes your hair by widening up your hair cuticle to dissolve the colour (melanin). The more you leave the cuticle open, then the more protein bonds (keratin), are destroyed. Ammonia or hydrogen peroxide are two of the most commonly used bleaches. However, there are not many other products that can help prevent damage. Do not get fooled by “peroxide-free” labels. This is just a sign that one more oxidizing ingredient was used. It could have been even more damaging to hair.

What happens if your hair is left bleached for too long?
The belief that bleach works better when left on longer is false.
Bleach should be left on hair for no more than 30 minutes. Bleaching your hair for longer than this can cause serious hair that includes brittle hairs.

Other Risks of Bleaching

  • You should not leave bleach on your hair too long. There are other potential dangers to this kind of process.
  • Your hair may lose all of its pigment and become white.
  • Hair could become white due to the oxidation process.
  • Your hair might become weak and less capable of retaining moisture.
  • One research revealed that bleaching caused hair to become much weaker. Even skin or scalp that was touched by bleach was affected.
  • Bleach can also make hair porous. This occurs when hair cuticles are too spaced too widely. It makes it challenging for the strands retain moisture.
  • Moderate porosity enables the hair look fuller and curls more easily. However, excessive porosity can cause hair shaft destruction and may lead to irreversible damage.
  • You could see your hair lose keratin
  • Bleaching can lead to hair loss of keratin. Keratin is a kind protein that makes hair.
  • Keratin is essential for hair structure. Without it, hair becomes brittle and hard to style. When bleaching, it is very difficult to avoid keratin losses.

Are there other precautions you can take?
Three important points to remember before you decide to bleach your hair yourself at home.

Perform a patch-test before you begin.
Perform a patch test prior to bleaching your hair at home. There may be an allergy you are not aware of. A 16-year-old girl was admitted to hospital in 2012 for a one percent of full-thickness chemical burn at her nape due to bleach. You can also test your hair prior to bleaching to assess if your hair condition is suitable for bleaching. If your ends are kinked, they will look frizzy or frayed, please do not lighten your hair. Instead, you can find a clear glossy to smoothen things until your ends are reduced and you have healthier-looking strands.

How to conduct a patch-test
You can test your skin with patch tests before applying a product topically, such as hair dye. Here’s how you can do a patch-test:

  • You can wash your forearm with an unscented, gentle soap and dry it.
  • A few drops of hair dye can be applied to an area on the inner forearm.
  • You should wait 24 hours.
  • If your skin patches are red, itchy, blistering or swollen you have an allergic reaction and should stop using the dye.
    NOTE: If your forearm is red or irritated within the 24-hour time period, wash it immediately with soap and warm water. Do not apply the dye to your head or hair.

Please read the instructions carefully
It is recommended that clients always follow professional procedures, such as wearing protective eyewear and gloves when doing bleaching at home. As in a professional hair salon, you should check for the hair’s lightness. It is recommended that the first check should take place after ten minutes. Then, you can go back and do another check every 5-ten minutes until you reach thirty minutes. If the results you are looking for do not appear after thirty minutes, rinse out the mixture and start over. Follow these directions and do not leave the bleach on for more than one hour.

Assess the type of hair your have
Some hair kinds cannot take the strength of bleaching. Bleaching should not be done if you have chemically treated your hair. This product is not for you and your head will literally turn to dust if it uses lightener. You can still bleach curly hair but you should be very gentle to the curly texture. When applying bleach, do not pull the curls.

How can I take care my hair after a bleaching treatment?
These tips can help you restore your hair’s softness and health after bleaching.

  • Use pre-shampoo conditioners three days before and after bleaching
  • Apply a post-colour bond builder treatment like Olaplex
  • Use a nourishing scalp mask
  • Use a thermal protector to protect your hair when styling it with an iron or blow dryer.
  • Use a light-weight protective spray or serum each day
  • After shampooing, use a conditioner for your hair
  • Be gentle with your hair, and do not brush too hard.
  • Wash hair with lukewarm to avoid drying out
  • Reconstructive products are recommended
  • You should wait between 6 and 8 weeks before bleaching again
