The tree isn’t the only thing that gets all gussied up for the holidays.

What about you, babe?

Whether your look is knot-ty or nice, you can add glitz — and make it stay put — with products from the Number 4 High Performance Hair Care collection.

The Sparkle and Spray gift set includes a 10-ounce can of Mighty Spray, which will add sparkle to your tresses while keeping your hairdo in place, plus Fluroro5 Elixer, a two-ounce super-shine treatment that replaces the dry winter doldrums with lots of gloss.

Even better, there’s a bonus. The gift set comes with a hair band set from Maddyloo that includes two contrasting hair ties, one black and one charcoal glitter, plus a black glitter headband. Just what you need to tie up an artfully messy bun, a fetching side ponytail or an uptown headband.

Based in California, Number 4 makes products that work super hard to style hair without sulfates, chloride or other harmful materials. Order online for delivery by Dec. 18 to ensure delivery by Christmas. Or check out the site to find a salon near you that carries the line. (MSRP: $49)
