Should I Wash My Hair Before Bleaching It?

3 mins

Andela Patrnogic

Should I wash my hair before bleaching it? This is a common question for those about to make the big decision to lighten your hair. Let’s find out the answer!

I was born a natural redhead, hair as bright and shiny as a copper penny. But over the years, my hair has gotten significantly darker. In my quest to return to my baby hues, I have had to experiment with bleach on several occasions.

As a result, I have found myself a sort of experiential expert on all things hair bleach, including how to properly prep and care for bleached hair. One of my biggest questions has been whether or not to wash hair before bleaching it.

Here’s what I’ve found:

What Effect Does Bleach Have on Hair?

For many years as a child, I was terrified of bleaching hair. Why? You know moms. Scary stories abound about that one girl who bleached her hair only to have it all fall out or the one about the girl whose bleached hair turned green after she swam in a chlorinated pool. It was all stories of destruction.

The truth is, yes, bleaching hair does essentially remove all pigment from your hair, stripping it of its melanin, which gives hair its darkness and/or redness.

However, removing pigment does not necessarily spell destruction, and thank goodness for that. Studies show 50% of women over the age of 25 dye their hair, with blonde being the most popular color. That's a lot of bleach.

Fortunately, the consensus among celebrity hairstylists is that, with today's technology and proper preparation and aftercare, you can have beautiful, healthy bleached hair.

To Wash or Not to Wash Hair Before Bleach

DO NOT WASH YOUR HAIR BEFORE BLEACHING IT. There, that was easy, right? A simple “no.” And here’s why: remember those horror stories from above? Right, those girls with falling-out hair and green hair had severely damaged hair.

You see, your hair and scalp produce natural oils that protect your skin and follicles from everyday damage like chlorine, the sun, and washing with chemical-laden, harsh shampoos and conditioners. Add bleach to all that natural damage, and suddenly you’re unwittingly bald. No one wants that.  

You want to refrain from washing your hair for several days before bleaching hair so that your scalp and hair have time to build up those natural, protective oils before you strip your hair of its pigment.

Your colorist may wet your hair before bleaching it, but that is often a natural part of the process that allows the colorist to control the amount of bleach and the lightening process. No professional will ever wash your hair before bleaching.

How to Care for Your Hair Before and After Bleach

So, you know not to wash it, but what should you do to care for your hair before and after leaping into lighter hair? 


    Yes, your skin and hair provide natural oils, but it cannot hurt, and it can only help to add an extra layer of protective oil to your hair and scalp before adding the harshest of harsh hair chemicals.


      If you have never bleached your hair before, try a patch test. You can get the kits online, and it will allow you to experiment with how your hair will be affected by the bleaching process before you invest what will likely be hundreds of dollars into your transformation. 

      Restore. Restore. Restore

        Enough cannot be said about the value of oil, and fortunately, a plethora of oils exist for your hair and skin needs. Once you have bleached your hair, you will need to help it rebuild the oils essential to protecting it. You can do that with a restorative shampoo and conditioner and/or with oil made to target restoration.

          I'm a huge fan of DIY for many things; bleaching is not one of them. Ask anyone (including those girls with green hair), and they will tell you to see a colorist and a good one at that. Yes, it will probably be pricey, but save your money in other DIY areas and save up for a colorist. Your hair will thank you. 

          Limit Sun Exposure

            I know. You want to enjoy your lightened locks during the summer, and I want that for you, too. But try to limit the time your hair is under the heat of the blazing summer sun. We all know of the damaging effects of long-term sun exposure, and with bleached hair, this damage is magnified. Invest in cute summer hats to be safe.
