How Often Should You Get Your Hair Cut?

“Regular trims help reduce breakage,” says Michelle Henry, MD, a board-certified dermatologist and the founder and CEO of New York City–based Skin & Aesthetic Surgery of Manhattan. “Cutting off those compromised ends prevents further splitting and helps preserve the overall strength and length of the hair.”

Regular haircuts aren’t just about aesthetics — they also play a crucial role in overall hair health.

“When the protective layer erodes, the underlying cortex becomes exposed, and the ends begin to fray,” says James Kilgour, MD, a board-certified dermatologist and the founder and CEO of KilgourMD, a company that focuses on scalp health. This leads to split ends (trichoptilosis), which can travel up the hair shaft and cause further breakage, he notes.

Regular trims eliminate damaged sections before they can split further, helping to maintain the integrity of the hair shafts — the strands of visible hair — that remain.

In general, experts recommend trims every six to eight weeks to keep hair healthy.

Nutrient gaps can also slow growth. “People with nutrient deficiencies may lack iron, biotin, or vitamin D, which can decrease hair growth and lead to increased hair shedding,” says Nicole Negbenebor, MD, a dermatologic surgeon with University of Iowa Health Care in Iowa City, who treats hair loss.

All of these factors — along with your hair texture, length, and whether you use hot tools or chemical treatments — influence how quickly your hair grows and how often it needs a trim. Here are some guidelines to follow.

For Short Styles and Pixie Cuts

Trims every four to six weeks can preserve the integrity of your ends, keep them healthy, and help maintain the overall shape of the cut, Dr. Kilgour says.

For Long or Fine Hair

Get a trim every eight to nine weeks, or every two to three months. Fine strands are more prone to breakage, so more frequent maintenance may keep your ends from thinning, notes Kilgour.

For Curly Textures

According to Kilgour, curly hair conceals damage and uneven tips better than other hair textures. The caveat? The hair fiber is more delicate, due to its natural bends, making it more susceptible to damage. Trims every eight to nine weeks to help preserve length and healthy ends.

For Chemically Treated or Heat-Damaged Hair

Regular use of hot tools or chemical treatments like keratin can weaken hair shafts and cause splitting, requiring a trim every six to eight weeks, Kilgour says.

Your hair can signal when it needs a trim — even if your next appointment is weeks away. Here’s how to tell when it’s time for a trim sooner than planned:

• Increased Tangling and Knotting Any friction to your hair, the use of hot tools, or getting regular chemical treatments can boost your risk of tangling and knotting, Dr. Henry says. When the outer layer of the cuticle wears away, hair loses its smooth surface and catches on other strands, making it more susceptible to tangles and knots.
• Loss of Elasticity and Shape Elasticity is your hair’s ability to slightly stretch before resuming its original shape. A loss of elasticity causes snapping and brittleness, Kilgour notes.
• Visible Breakage This can appear as frizziness, thinness, or uneven length, and it may be caused by repetitive heat exposure, chemical treatments, daily wear and tear from styling, or nutrient deficiencies, Kilgour says.

For happy, healthy strands, incorporate these expert-approved tips into your hair-care routine:

1. Handle your hair with care. Rough brushing or towel drying can cause microfractures in the cuticles, leading to split ends, Kilgour says. Instead, use a wide-tooth comb to gently detangle wet hair, and be gentle with your towel drying.
2. Minimize hot tool usage. Limit your use of hair dryers, straighteners, and curlers to once per week to help maintain the structural proteins that strengthen hair.

   When you do use hot tools, keep heat settings at low or medium.

3. Apply a heat protectant. To safeguard your hair from hot tools, Dr. Negbenebor suggests using a heat protectant. These styling products are available as sprays, creams, and serums that create an insulating layer between your hair and the hot styling tools.
4. Condition regularly. A conditioner helps alleviate friction and smooth the cuticles, so make sure to use it after every shampoo.

   It’s recommended that you wash your hair five or six days a week for optimal scalp health.

5. Switch your pillowcase or use a headscarf. Negbenebor recommends sleeping on a satin or silk pillowcase or wrapping hair in a satin or silk scarf. Unlike rougher fabrics like cotton, satin and silk create less friction overnight, reducing the risk of breakage and damage while you sleep.

• Experts generally recommend trimming your hair every six to eight weeks. However, the ideal frequency for you depends on your hairstyle and texture, as well as whether you use hot tools or chemical treatments.
• Daily washing, brushing, hot tools, and UV exposure can cause split ends that damage and weaken hair.
• Regular trims prevent frayed ends and preserve the integrity of the hair shaft.
