Because prom season is generally warm and you’ll be sweating all night on the dance floor, a good product to invest in is an anti-humidity hairspray. Locking in moisture and keeping out frizz, these products combat sweat and heat to keep your prom hair looking flawless throughout the long night.
“One of my favorite products for this purpose is Alterna’s Bamboo Smooth Anti-Humidity Hair Spray, which is pretty affordable at $18, and is available at Sephora or on Sephora.com. The spray is lightweight and the hold is flexible and not sticky. It extends the life of any hairstyle by a considerable amount of time. It’s also eco-friendly, which is another added bonus, says Gocha Hawkins of Gocha Salon in Atlanta, Georgia.
Douglas David, managing partner of Douglas Carroll Salon weighs in as well on some products to use prior to prom:
 Shampoo your hair the day before the prom. Douglas David recommends using KMS Free Shape shampoo, as this product will help transform your hair easily from curly to straight or straight to curly.

 When it comes time to dry your hair after shampooing, make sure to use a product that will boost volume from the roots. Douglas David recommends using the Goldwell Double Boost Rootlift Spray, which focuses specifically on root volume making the hair look fuller.

·Before you actually style your hair for prom, make sure to use a dry shampoo. Products such as KMS California Hair Play Makeover Spray or TG’s Catwalk Session Series Transforming Dry Shampoo will give your prom hair texture to maintain hold through the evening.

It is always a great idea to keep travel size products nearby so that your hair can be retouched throughout the evening. Travel size dry shampoos and hairsprays are excellent choices. Consider using KMS California Dry Extreme Hairspray to help maintain your look.
You can also keep KMS California Flatout Anti Humidity on hand as a way to add shine and reduce frizz or flyaways that happen during the night. At the same time, KMS Hair Play Dry Wax is a great go-to option for people with textured short hair or curl, as the produce will give hair the hold and flexibility it needs.
