Hally HairLightener Spray, Lighten Up for Brunettes - Gentle & Easy to Use Sun Hair Lightening Spray Lightens Hair Up to 2-3 Shades - Hair Brightening Spray for Healthy, Vibrant & Sun-Kissed Look

I do my own balayage at home (I know, crazy) and I love this product for when my roots start to grow out. I'll just take wet hair from the shower and spray this in a few small sections on the top, blowdry it and see an immediate slight lightening of those sections. The result looks subtle and natural. For my medium auburn hair, it only lightens a couple of levels so if you're looking for a major difference, you probably need a highlight kit. But for the price point, I'm happy with the outcome. As other reviewers have said, it leaves your hair soft, not crunchy like some spray-in lighteners, and it doesn't have to be washed out after use.

Bottle top was not on tight. Product leaked into packaging. Waste of money

This product is a godsend! A few sprays before I blow dry and I am able to extend the time between pricey colorings. It give the look of a beach vacation in 3 minutes.

I bought this for the winter months when the UV was low but I still wanted to keep my summer highlights. I sprayed the product on damp hair out of the shower then blow dried my hair on the hottest setting possible. I've also tried the Sun Bum hair lightener with this method and I prefer this product much more. However, since there is no UV it does take much longer and it left my hair feeling overall more brittle with split ends though I can understand why.

Love that this doesn't have harsh chemicals and actually works! I love using it to lighten up with the blow dryer once every couple of weeks!

You have to use a lot and pass through your hair with A LOT of heat in order to see any color change.

Does nothing.

This is honestly such a great product l, my hair used to be dark brown and now it’s so much lighter. Way better and cheaper than going in and getting highlights
