Leave your roots alone. Damage caused by bleaching and dyeing is worse when it's close to your scalp and follicles. You should let your roots grow out at least a half an inch before getting a touch up. This can help minimize damage.^{[4]

- Hair grows about a half inch per month on average, though this can vary by person and time of year. This means that it’s best to get a touch up every 4 to 6 weeks.

Take extra care of your hair after dyeing. Salon-dyed hair with professional products is probably the best way to go – it uses less harsh chemicals than at-home treatments. If you dye your hair at a salon, though, it may still need extra care afterwards. Talk to your stylist about how to give your hair extra TLC after dyeing.
- Ask your stylist for recommendations for moisturizing conditioners and other at home treatment options. Hair dye can cause hair to be dryer than normal.^{[5]

Using Home Remedies

Use vinegar and water. Rinsing hair with vinegar and water helps lighten hair for some. Try mixing one part vinegar with six parts water. Then, rinse your hair for 15 minutes. Apple cider vinegar may work better and has a nice smell.^{[8]

Add salt to your hair. Simple table salt may have an effect on hair color. Many people notice their hair gets lighter in response to swimming in salt water. Try adding one part salt with five parts water. Rinse into your hair and let sit for 15 minutes. Then, rinse and wash as usual.^{[9]

Crush vitamin C tablets and add them to your shampoo. Vitamin C can lighten your hair and may actually improve its overall health. Take 8 or 9 vitamin C tablets, which you can purchase at most drug stores, and crush them. You can do this by putting them in a plastic bag and then rolling the tablets into a powder using a rolling pin. Mix this into your shampoo. Use the shampoo as usual over the next few weeks and see if you notice an effect.^{[10]

Then, rinse out your hair with clear water.^{[11]

Try honey. If you're not into dyes or chemical treatments, many people swear by honey as a natural means to lighten hair naturally. Honey is deeply moisturizing but contains trace amounts of hydrogen peroxide that can help lighten dark hair. Like vinegar and water, though, this methods doesn’t work for everyone.
- Mix a small amount of honey into water or vinegar before applying it to your hair. Honey is sticky and difficult to wash out, so you want to dilute it before adding it to your hair.^{[12]

- Coat your hair in a blend of honey and water or vinegar. Put on a shower cap and leave the mix in overnight. Wash out in the morning and see if you notice any results.^{[13]

- Make sure to condition your hair regularly if using this treatment. Lemon juice is very acidic and will therefore dry out hair.^{[14]

Use hydrogen peroxide. Hydrogen peroxide is a chemical that can lighten hair. It is very strong, though, and can make your hair feel dry and brittle. Use it very carefully. Put some hydrogen peroxide in a spray bottle and spray it even over your hair. If necessary, use hair clips to pull hair out of the way to get hard to reach sections. Leave in for 30 minutes and then wash out with cold water.^{[18]

Lightening Dyed Hair

1
Use a clarifying shampoo. If you had a dye job you dislike, scrub your hair with a clarifying shampoo as soon as possible. Clarifying shampoos contain powerful surfactants capable of stripping away grime, chemicals, and hair dye.
- You can find a clarifying shampoo at most supermarkets or drug stores. Follow any instructions on the bottle when applying clarifying shampoo to your hair.^{[19]

- Clarifying shampoo can dry out hair, so you might try following it with a moisturizing shampoo. Be sure to condition your hair afterwards to prevent dry, cracked hair.^{[20]

Remove semi-permanent dyes with vitamin C powder and shampoo. If a clarifying shampoo doesn't do the trick, you can remove semi-permanent dyes by adding vitamin C powder to existing shampoo. This can help lighten a dye job by lifting some of the existing color from your hair.^{[21]

Generally, bleach doesn't need to sit on the hair for any longer than 45 minutes to an hour. It will stop processing after that time. Refer to the instructions that came with your bleach kit for the exact recommended time.

Sunlight naturally lightens hair. If you spend 1-4 hours out in the sun for a few weeks, you should notice a change in your hair's shade. Consider using honey or cinnamon to lighten you hair also.
