How Exactly Does Bleaching Work?
Bleaching oxidizes melanin pigments in the hair and lightens its color. Bleach contains oxidizing agents like hydrogen peroxide and ammonia. These are chemically aggressive agents and can damage the hair shafts if you repeat the treatment (1).
While manufacturers claim their products are peroxide-free, it does not mean that they are free of harsh chemicals. It only means that the bleaching formula has some other bleaching agent, which will probably be just as harsh, if not worse.
But how bad is the bleaching process? Check out some side effects of bleaching your hair twice in the next section.
What Are The Potential Harmful Effects Of Bleaching Your Hair?
Whether you get the help of an expert or do it yourself, hair bleaching has the following side effects:
- Scalp Burns: Bleaching can leave your scalp itchy and damaged (2). If you feel an itch or burn on the scalp while bleaching, rinse it off immediately.
- Dry, Frizzy, And Coarse Hair: Bleaching makes the hair dry, frizzy, and rough. To counteract this and reverse the damage, you can apply coconut oil and go for conditioning treatments.
- Discolored Hair: This happens if you do not mix the bleaching ingredients in the right amounts.
Bleaching is an aggressive (and at the same time) delicate process for your hair. You can bleach your hair twice, but not twice in a row on the same day as it may cause hair breakage and hair fall. You may even lose hair in clumps, and each time you touch your hair.
So how long should you wait before bleaching your hair the second time around? Find out below!
How Long Should You Wait Before The Second Bleaching Session?
Try not to bleach your hair twice a week. Wait for about 4 to 6 weeks before bleaching it again.
This waiting period allows your hair to rest, rehydrate, and recover from the effects of the first bleaching session. Before the second bleaching session, continue to oil your tresses and undergo conditioning treatments. This will keep your hair in better shape.
In the following sections, we have covered the basics of bleaching and how to prepare your hair for the next bleaching session.
How To Bleach Your Hair – A Beginners Guide
Apply extra virgin coconut oil to your hair the night before bleaching and let it absorb the oil overnight. Coconut oil penetrates the hair, keeps it moisturized, and can minimize the harsh effects of bleach (3).
Get The Materials Ready
The following day, keep all the materials ready in one place. These include:
- A non-metallic bowl and a brush
- A lightener and developer
- A toner
- Sulfate-free shampoo
- Deep conditioner
- Purple shampoo and conditioner
- A large comb
- A rat tail comb
- An old t-shirt
- A plastic cap
Bleaching Instructions: A Step-By-Step Guide
- Part your hair into smaller sections. Wear gloves and cover the shoulders with an old T-shirt to avoid any stains.
- Mix the lightener and developer according to the instructions on the bottle.
- Start applying the mixture from the back of the head and move towards the front. Apply it evenly and leave about 5 cm off the roots. Put on a shower cap.
- Leave it on for about 20 minutes. Then, apply the mixture to your roots, and let it sit for about 10 minutes. You may skip this part.
- Shampoo your hair and follow up with a hydrating conditioner. Use room temperature water for rinsing.
- Let your hair air dry. Now, apply an expert-approved toner to get the perfect tone and level of brightness.
- If the result is too brassy for your choice, apply a purple shampoo and conditioner.
In some cases, your hairdresser might recommend a specific shampoo and toner and hydrating, protein-rich treatments to maintain your hair health. Remember to follow a well-balanced diet to keep your hair strong, smooth, and shiny (4).
Wait for at least a week or two before you bleach your hair again.
Prepping Your Hair For The Second Bleaching Session
- Between both the bleaching sessions, strengthen and moisturize your hair so that it is ready to face the second round of bleaching.
- Apply extra virgin coconut oil from the middle of the hair and let it soak the oil. Do it every alternate day.
- Avoid heat styling equipment, such as flat irons and blow dryers.
- If you notice split ends, trim them before the second session.
- Similar to the first session, apply coconut oil the previous night and prepare your hair by giving it that extra boost of hydration.
Bleaching Instructions: A Step-By-Step Guide
- Bleach your hair following the same steps mentioned in the first round of bleaching.
- In the second round, leave the mixture on for only 10 minutes and then wash off.
If you feel that your hair has suffered a lot of damage in the first bleaching session, wait for a month before bleaching it again.
Since bleaching your hair twice can do some damage to your locks, you need to be as careful as possible. Keep the following bleaching tips and warnings in mind.
Tips And Warnings
- Be Mentally Prepared: If you wish to bleach your hair, be prepared for the fact that it will need higher-than-usual maintenance.
- Do Your Homework: Understand your hair type and invest in quality hair care products. Consult a hairstylist, do your research online, and take serious care of your tresses.
- Proceed One Step At A Time: You cannot get platinum or ash blonde hair in just one session. Avoid bleaching the hair too frequently. Maintain a gap of at least two weeks between sessions. With each session, you can lighten your hair up to three tones.
- Take Professional Help To Minimize Damage: If you think your hair has suffered damage after the first round of bleaching, seek professional help. Your hairstylist can do a strand test to see how long the bleach should stay the second time around. For best results, get the second round of bleaching done by a professional.
- Take Care Of Your Hair Post-Bleaching: Bleaching makes your hair brittle and fragile. Take the necessary after-care to prevent further damage.
- Consider The Ideal Waiting Period: If you can wait it out, go for another bleaching session only after four to six weeks, which is sufficient time for your hair to rest and breathe.
- Never Apply Unevenly: When applying the bleach, make sure to apply it evenly for the best results.
- Keep An Eye Out For The Time: Leaving the bleach on for too long or too short can result in undesirable results. Make sure to keep a timer on.
Bleaching your hair twice on the same day is a big no-no. Get expert advice if you have never bleached your hair before and take proper care of your hair before and after bleaching.
