The simplest way to protect your hair in a tanning bed is to cover it completely with a towel, cotton wrap, or tanning cap. Tanning beds emit up to 12 times more UVA radiation than natural sunlight, and that concentrated UV exposure breaks down the proteins and pigments that keep hair strong, shiny, and colorful. A few easy steps before, during, and after your session can prevent most of the damage.
Why Tanning Beds Are Hard on Hair
Hair damage from UV exposure, sometimes called photoaging, involves several things happening at once. The radiation breaks down keratin, the structural protein that gives each strand its strength. It oxidizes the lipids that form your hair’s natural moisture barrier. And it degrades melanin, the pigment responsible for your hair color. The result is hair that looks faded, feels dry and rough, and breaks more easily.
What makes tanning beds particularly damaging compared to a day at the beach is the intensity and type of light. Tanning beds emit predominantly UVA rays, accounting for up to 98% of their radiation output. UVA penetrates deeper than UVB and is especially effective at degrading color pigments and the outer cuticle layer of hair. Because the bulbs surround your body at close range, your hair gets a concentrated dose from multiple angles, not just from above like sunlight.
Cover Your Hair During Every Session
Physical barriers are the most reliable protection. A small cotton towel wrapped around your hair works well and costs nothing. Tuck all of your hair inside, including any pieces around your hairline that tend to escape. If you prefer something purpose-built, tanning caps and shower caps designed for UV environments stay in place without slipping. Avoid materials that trap excessive heat against your scalp, like thick wool or synthetic fabrics that don’t breathe. A lightweight cotton or microfiber wrap strikes the right balance.
If your hair is long, twist it into a loose bun on top of your head before wrapping. This reduces the surface area exposed to any light that might sneak through the edges of your cover. For short hair that’s difficult to tuck away, a snug-fitting cap is the easier option.
Use a UV-Protective Hair Product
When covering your hair isn’t practical, or as an added layer of defense, apply a leave-in product with UV filters before your session. Hair sunscreens and UV-protective sprays work by absorbing or reflecting ultraviolet light before it reaches the hair shaft. Look for products specifically labeled for UV or sun protection rather than general heat protectants, which are formulated for blow dryers and flat irons, not ultraviolet radiation.
Apply the product from mid-length to ends, where hair is oldest and most vulnerable. The ends of your hair have endured the most cumulative damage over their lifetime and lose their protective cuticle layer fastest. A light, even coat is enough. Heavier application won’t add much extra protection and can leave hair looking greasy.
Protect Color-Treated and Bleached Hair
If your hair is dyed or highlighted, tanning beds pose a double threat. UV radiation fades both permanent and semi-permanent color noticeably faster than regular sun exposure because of the concentrated UVA output. Blonde and light-colored dye jobs can develop a brassy or yellowish tone. Reds and coppers fade the fastest of any color family.
Bleached hair is structurally weaker than untreated hair because the bleaching process has already stripped away some of the protective cuticle and internal proteins. Adding intense UV exposure on top of that accelerates breakage. If you’ve recently bleached or lightened your hair, covering it completely during tanning sessions is worth the minor inconvenience. Even a few sessions without protection can undo the vibrancy of a fresh color treatment.
Extra Precautions for Hair Extensions
Hair extensions are even more vulnerable than your natural hair. Extension hair doesn’t receive any natural oils from your scalp, so it lacks the thin lipid layer that provides a small amount of built-in UV defense. UV rays cause extensions to become dry and brittle faster than natural hair, eventually leading to breakage and noticeable color fading.
The bonds themselves can also suffer. Heat and UV exposure soften keratin-tipped bonds and weaken the adhesive on tape-in extensions, which can cause them to slip or shed prematurely. If you have extensions, always cover your hair fully during tanning sessions. After your session, apply a lightweight moisturizing oil or serum to the mid-lengths and ends of the extensions to replenish moisture.
Post-Session Hair Care
What you do after tanning matters almost as much as what you do during. UV exposure strips moisture from hair, so rehydrating quickly limits the cumulative damage. Rinse your hair with cool water after your session if possible. Cool water helps the cuticle layer lie flat, which locks in whatever moisture remains and gives hair a smoother appearance.
Follow up with a moisturizing conditioner or a leave-in treatment. Products containing natural oils like argan, coconut, or jojoba are effective at replacing the lipids that UV radiation breaks down. Once a week, a deep conditioning mask can help repair hair that’s already showing signs of dryness or roughness from regular tanning.
Avoid using hot styling tools immediately after a tanning session. Your hair has already absorbed a significant amount of radiant energy, and adding heat from a flat iron or curling wand on the same day compounds the protein damage. Give your hair at least several hours, ideally until the next day, before applying direct heat.
Habits That Reduce Long-Term Damage
Spacing out your tanning sessions gives hair time to recover between UV exposures. The protein loss and cuticle damage from UV radiation are cumulative, meaning each session builds on the damage from the last. Tanning every other day rather than daily, or reducing session length, meaningfully lowers the toll on your hair over weeks and months.
Keeping hair well-moisturized as a baseline also helps. Hair that starts a tanning session already dry and porous absorbs more UV damage than hair with an intact moisture barrier. Regular conditioning, limiting chemical treatments, and minimizing heat styling all build resilience that pays off every time you step into the bed. The goal is to keep your hair’s cuticle layer as smooth and intact as possible so it can do its job as a natural shield.
