Today I'm going to take a moment to talk about a haircare staple I first was introduced to last spring with a Sephora perk. Bumble and Bumble Thickening Hairspray is expensive ($28/8oz), but I've been using the same bottle for at least ten months and have probably another year's worth of hairspray in it.
Bumble and Bumble Thickening Hairspray is described as a moderate-hold product. I love that it's lightweight, non-aerosol, and combats humidity well. It takes very little of this formula to create the desired effect. It lasts through most of the workday, and is non-sticky.
I used several 1-oz bottles prior to splurging on the full size. I'd recommend doing the same. This has been better than my prior favorite, Elnett.
You can find Bumble and Bumble Thickening Hairspray at Sephora, Blue Mercury, or anywhere that has Bumble and Bumble products.
