If your hair isn't naturally a light blonde, all of those trendy bleached and rainbow colored looks are going to require some serious bleach. Stopping to ask yourself, "What does bleach do to your hair?" is a wise move before hitting up a stylist or purchasing a box so you can know what to expect. Since you're literally changing the chemical composition of your hair, you want to be as informed as possible.
In a seriously amazing video for Chemical and Engineering News' "Speaking of Chemistry" series, host Matt Davenport explained exactly what happens when you bleach your hair. To summarize, bleach breaks into your hair shaft and reacts with the pigment molecules (basically destroying them so you're left with light hair). To be able to tackle the dark pigment, bleach has to break down the natural fatty acids on your hair shafts, which is what can leave your hair brittle.
For more specifics on what can happen after you've bleached your locks, hair specialist Robert Dorin of True & Dorin Medical Group shared details with Huffington Post. He said, "Hair becomes frayed making it brittle, dry, and more susceptible to tangling together, causing a bird's nest type of effect." Womp.
But, that doesn't mean you can't bleach it successfully. Dorin mostly advised, "You should gradually lighten hair (making multiple trips to the salon) instead of going from dark to platinum in one step. This will most likely just completely destroy the hair." Patience will be rewarded, my friends.

I've also scouted out a few products and tips to help hydrate your strands after bleaching if you decide to go for it!
1. Use Heat Protectants
Since your bleached hair will be extra vulnerable, Dorin recommended always using thermal protectant sprays before heat styling tools.
2. Try Purple Shampoo

Cosmopolitan warned that without purple shampoo, your blonde locks will turn a seriously brassy hue. Speaking from experience, this could not be more true.
3. Buy Products Designed For Bleached Hair
Your standard conditioning masks won't cut it anymore. XoJane advised investing in proper post-bleach care products to keep your hair soft.
4. Consider A Pre-Shampoo Deep Conditioning Treatment
That's right: pre-shampoo. This will help protect your more delicate strands from snapping when you do need to give them a good shampooing. Philip Kingsley advised using it weekly to boost shine and strength.
5. Reach For Dry Shampoo
Since shampoo can strip your hair of oils, give your hair as long as possible in between shampoos by shaking in dry shampoo.
6. Protect With UV Products
Bleached hair doesn't need to be even more dried out. Before you hit up a sunny spot, spritz with UV spray or pop on a hat.
7. Trim Frequently
With bleached hair bound to be a little more dry, keeping up with regular trims is essential to quelling split ends.
8. Avoid Heat Styling
For at least the first few weeks, try to avoid curling irons, blow dryers, and flat irons that add damage to your already "fried" hair.
9. Use A Wide Tooth Comb
Fluffy round brushes can cause more breakage than a gentle, wide tooth comb. Since your hair needs all the TLC it can get, invest in a quality comb to brush with.
