Lightening hair with hydrogen peroxide and baking soda

I’m gonna try to lift my hair a shade or two with hydrogen peroxide because I just bleached it and RAN OUT OF BLEACH so now some parts of my hair are light light blonde and some are still quite dark and it looks noticeable enough to me to bother me. however, at this point, putting more bleach on my head is probably not a great idea, SO. I think hydrogen peroxide will do it since I’ve had great results with the product Sun-In before, and the only reason I didn’t buy it was because I can’t find it at any store right now :unamused: half the stuff I’ve read says hydrogen peroxide + sun/heat will work and the other half says do a mask with baking soda??? but why?? what does the baking soda do?? what would be better, to just use heat or to mix it with baking soda? I literally only need it lifted a shade or two.

if anyone is interested in this topic, I ended up spraying my hair down with 3% hydrogen peroxide not mixed with anything and then I hit the tanning bed for 8 minutes and that did the trick lol

@Kitten_Pajamases wow I’ve never heard of mixing hydrogen peroxide with baking soda before…and you’re right I’m not quite sure what that would do? I know baking soda is a natural bleaching agent, but I’ve only heard of it used on the skin, and definitely not hair.

So it worked for you then?? I’ve always wanted to dry hydrogen peroxide on my hair, but I’ve been deathly afraid…plus I have pretty dark hair so I’m not sure it would work at all

I didn’t know that about baking soda! I just thought people used it on their skin for exfoliating. so I was like “why would I need to exfoliate my hair to lighten it.”

and, my hair is naturally dark blonde so it’s easy to use hydrogen peroxide to lighten it. if your hair is dark, I wouldnt suggest using it cause it might turn your hair orange or something…but maybe chamomile tea or lemon juice alone could give you some subtle highlights? but I would research that first! lol

Just be super careful when you do this, as it can go completely wrong if you don’t do it the right way. Thankfully, it worked for you @Kitten_Pajamases, but I remember I had this friend back in high school that did this and she ended up with big, weird chunks of “bleached” hair…wasn’t even at all. Then again I guess we were in high school so there was that lol, but still…make sure to saturate ALL the hair so you don’t end up looking like a zebra :stuck_out_tongue:

yeah and definitely do a test strand first because I have no idea what would happen to darker hair :sweat_smile: this has been a disclaimer lol.

Thanks @Kitten_Pajamases!! I actually did this the other week (wanted to take a before and after and totally forgot…d’oh!) and it frikken worked! Was I super scared? YOU BET haha, but you know what? It’s only hair and it WILL grow back, plus my hair is already light, so there was not much that could’ve went wrong!

I actually applied the hydrogen peroxide to my hair and laid out in the sun for about half an hour! I got the cutest highlights ever and saved so much money in the process!
