    Taking steamy showers
    Hot water dehydrates strands (just like skin), leading to dry, brittle hair that’s more prone to snap and fall out, explains Ryan Welter, MD, a Boston-based hair transplant surgeon. “Not only are you washing your hair’s protective oils down the drain, but the heat throws your scalp's pores into overdrive to keep up with oil production, which can damage the root and lead to additional shedding.”

    Using hot styling tools
    Scorching temps damage the proteins that make up your hair and its protective cuticle. “Once the cuticle is damaged, the moisture balance is disrupted and your hair is more prone to breakage,” says Dr. Bauman.

    Crash dieting
    Starving yourself forces the body to direct its energy (the little it has) towards essential functions—like helping your heart and brain work—rather than making hair. In fact, when diagnosing anorexics, one of the top symptoms is severe hair loss, says Paradi Mirmirani, a Vallejo, California dermatologist specializing in hair disorders.

    Mishandling wet hair
    Our strands are never more fragile—and prone to breakage—than when they’re saturated with H2O, since the protective cuticle is slightly raised. Brushing or combing locks in the shower, then following with aggressive towel-drying, create the perfect storm for snapping it off.

    Wearing tight hairstyles
    If a tight ponytail or braid is your go-to, beware: Sporting these styles puts excessive tension on the hair follicles, damaging them and creating scars that destroy them permanently, says Doris Day, MD, a New York City-based dermatologist specializing in hair health. This can lead to traction alopecia, a condition that permanently weakens the follicle and makes it impossible for hair to grow.

    Using long-lasting hold styling products
    If your hairspray or gel claim All-day Mega-hold, they’re actually making your locks harder to hold on to. “These are usually high in alcohol, which makes hair dry and brittle,” says Dr. Mirmirani. “Once you comb or brush your hair, that residue causes the hair to break and fall out.”

    Taking oral birth control pills
    If you’re one of the many women who are sensitive to hair shedding or thinning due to hormonal changes, the wrong oral birth control can weaken your hair. “A pill that contains androgens can cause hair loss for someone who’s ‘androgen sensitive’ and doesn’t know it,” says Dr. Bauman.

    Soaking up the sun
    Even if you’ve (wisely) given up tanning, chances are your hair is still exposed to UV rays, which eat away at the strength and elasticity of your hair. “Prolonged UV exposure causes the layers of the cuticle to weaken and break, resulting in brittle hair that can lead to hair loss,” says Dr. Bauman.

    Not washing hair often enough
    Now that dry shampoo is a staple in most of our beauty arsenals, it’s easier than ever to skip a few days between washing. Convenient? Yes. But not so great for your hair: “A buildup of product or excessive dandruff on the scalp has been shown to clog hair follicles, and if it’s bad enough, it can be difficult for hair to grow,” says Dr. Day.

    Taking certain medications
    Certain medications (like statins, anti-depressants, anti-anxiety agents, anti-hypertensive medications) or hormones (like thyroid replacement drugs) can cause hair loss. “These can disrupt or interfere with the normal cycle of hair growth, causing hair to go into a resting phase and fall out prematurely,” says Dr. Bauman.
