$50 gift card, what do I use it for??

Hey everyone, I got a gift card as a credit card reward and don’t usually shop at Ulta as I am not a big makeup person but I do love hair care and skin care, I have wavy hair I’m trying to amp up so maybe hair products and I have some acne/combination skin so maybe skin care? Maybe teeth whitening stuff if anyone has any favorites or holy grail products I’d love to hear them regardless, lmk! Thanks!
