FLAT HAIR NO MORE

If you have fine, fragile, or flat hair, K18 AstroLift Reparative Volume Spray is the game-changing holy grail you have been waiting for. Most volumizers force you into a frustrating trade-off: they give you temporary lift at the expense of sticky, crunchy, starchy hair that feels like cardboard by midday. AstroLift completely rewrites those rules by delivering a stunning 2.5x more all-over volume that stays incredibly soft and touchable.

does nothing

added no volume to my hair and if anything i noticed that it made my hair greasier so i had to go in with the dry shampoo from this brand too which i loveeee so my expectations were high. and the smell is absolutely horrendous like it actually made me want to throw up
