1. Tight Braids: While these are super trendy (and pretty), Jeanie says they 鈥渃an cause serious breakage, specifically around your hairline.

2. Slicked-Back Hair: This is Jeanie鈥檚 personal favorite hairstyle to keep her bangs out of her face during the sticky summer months, but the chemicals in gel can break down your follicles if used too much. And forget about brushing the style out while it鈥檚 still crispy! She advises that you instead 鈥渞inse out in the shower with a detangling conditioner鈥 to prevent unnecessary breakage and countless split ends. (Photo via Frazer Harrison/Getty)

3. Pin-Straight Hair: While all heating tools will cause damage, it鈥檚 wise to 鈥渋nvest in professional tools to keep your hair in the best condition 鈥 a natural bristle brush, a tourmaline dryer with a nozzle and a good heat-controlled digital flat iron with plates that glide. Always use a heat protectant on your hair before applying heat, like TRESemm茅 Thermal Creations Heat Tamer Spray ($5).鈥 (Photo via Tristan Fewings/Getty)

5. Wet Hairstyles: Sure, it might be easier to throw your hair in an updo while still wet, but it will cause significant breakage and splitting if this is your go-to 鈥榙o. If you鈥檙e in a time crunch, Jeanie suggests adding a styling creme and using large hairpins that grip hair 鈥 they鈥檙e gentler than drugstore elastic bands. (Photo via Alexander Tamargo/Getty)

6. Habitual Ponytail: It鈥檚 easy to get in a hair rut, but putting your hair in a ponytail in the same position day after day can cause damage. Jeanie suggests 鈥渕ixing up different ways to style your pony. You can do sleek and low with a barrette, loose to the side with a scarf or high at the crown with a piece of leather. Get some fun accessories and make sure to always switch it up if the ponytail is your signature.鈥 (Photo via Frazer Harrison/Getty)

7. Ballerina Buns: Try to avoid a bun for your daily look. A looser, messier bun will cause less damage, but if you prefer the tight ballet look, ditch the hair tie and fasten with large pins only. (Photo via Michael Buckner/Getty)

8. Super Long Locks: The longer your hair is, the older it is, making it more prone to breakage and splitting. 鈥淢ake sure to give extra care to those ends, since they鈥檙e the oldest and most fragile (average growth is 1/4 inch per month!). Trim ends every 6-8 weeks, and try to skip the heat tools daily,鈥 says Jeanie. (Photo via Michael Loccisano/Getty)
