If you’ve ever used Sun In, then you’ve likely used lemon juice to lighten your hair.
Byrdiegot the low-down on using the yellow citrus fruit to brighten your hue.
Guy Tang, colorist and founder of#mydentity, told the publication howlemon juiceworks to lift color.

Of course, it doesn’t all happen at once.
It takes a few applications before you’ll see noticeable results from squeezing the tart liquid on your mane.
With each tool, some of the hair cuticle breaks down.

If you have lighter hair, lemon juice will work when exposed to sunlight (viaHealthline).
It’s more subtle than bleaching, which means it may look more like natural sun highlights.
Another positive for the treatment is the anti-fungal properties of lemon juice may help with scalp itchiness and flaking.
Both Tang and Monahan warned that this concoction might make hair feel dry and brittle (viaByrdie).
Rinse out the lemon juice as soon as it’s dry and apply your favorite leave-in.
If you’re ready to take the plunge, grab some lemons and enjoy some sun.
