How Long Before a Spray Tan Should You Shave?

Shave about 24 hours before your spray tan. A same-day shave leaves hair follicles open and skin a little raw, so the solution can settle into the openings as tiny dark dots and fresh nicks can sting. Shaving the day before gives your skin time to close up and calm down.

That one rule handles most of it. What follows is the reasoning, the technique that gives you the smoothest base, and how to shave during the week after without wearing the tan away.

What a razor does to your skin

A razor does two things at once. It cuts the hair, and it scrapes off a thin layer of surface skin along with it. That second effect is why shaving counts as a form of exfoliation, and why it belongs in the same 24-hour window as your scrub. The day before your tan, that is a good thing: it clears the loose, dry cells that would otherwise take color unevenly.

Right after a shave, though, the skin is at its most open. Follicles are freshly emptied, there can be small nicks you cannot see, and the surface is slightly irritated. A spray tan applied in that state behaves differently from one applied to calm skin.

The dots

Open follicles are tiny wells. Solution collects in them, and because DHA reacts wherever it sits, those wells can develop a little darker than the skin around them. On legs, it reads as a sprinkle of dark pinpoints, especially visible from close up. Giving the follicles a day to settle makes that much less likely.

The sting

Freshly shaved skin, and especially fresh razor burn or nicks, can sting when solution touches it. It passes quickly, but there is no reason to sign up for it. Shave the day before and you skip it.

How to shave for the smoothest base

1. Exfoliate first. In the same shower, use a mitt or washcloth on your legs and any areas you plan to shave. It lifts dead skin and helps the hair stand up for a closer shave. The full method is in Should You Exfoliate Before a Spray Tan?
2. Use a sharp blade. A dull razor drags and needs more passes, which means more irritation. If you cannot remember when you changed it, change it.
3. Use shaving gel or cream, not soap or oil. Gel gives glide without leaving an oily layer behind. Shaving oils are lovely, but you want your skin clean of oil by tan day.
4. Go with light pressure and few passes. Let the blade do the work. Over-shaving the same strip is how you get razor burn.
5. Rinse well and moisturize lightly. A plain lotion the night before is fine. By your appointment, it should be fully absorbed, and nothing new goes on that day.

Areas people forget

• Underarms. Shave the day before, and don’t put deodorant on the day of your tan. Bring it and apply it after your first rinse.
• Arms and the tops of the hands. If you shave them, they follow the same 24-hour rule.
• The bikini line. This is where skin is most likely to react to a same-day shave. Give it a full day.
• Your face. If you shave or dermaplane anywhere on your face and are having it tanned, do that the day before as well.

If you get razor bumps

Some skin reacts to any shave with small red bumps, especially on the bikini line, underarms and the backs of the legs. If that is you, the 24-hour gap matters even more, and a few small changes help:

• Shave in the direction the hair grows rather than against it.
• Rinse the blade after every stroke so it stays clear.
• Finish with cool water and a plain, fragrance-free lotion that evening.
• If bumps are still there on tan day, mention it when you arrive so those areas can be handled lightly.

Persistent bumps, ingrown hairs or a rash that won’t settle are worth showing to a dermatologist. They are skin questions first and tan questions second.

What if you forgot?

It happens. You realise at 9 PM the night before that you have not shaved. Shaving that night is still far better than shaving on the morning of. If it is the morning and you are standing in the shower with a razor, it is usually better to leave short stubble than to shave right before you walk out the door. Fine stubble does not ruin a tan, and you can shave it after your first rinse.

If you wax instead of shaving, the timing is different, because waxing is harder on the skin. That is covered in Waxing, Laser & Spray Tans: The Right Order and Timing.

Shaving during the week after

Once your tan has had its 8 hours and its first lukewarm, soap-free rinse, you can shave. Because a razor removes a thin layer of skin each time, shaved areas will fade a little faster than the rest of you. You can keep that small:

• Use a fresh, sharp blade so one pass is enough.
• Use a gentle gel and light pressure.
• Keep the shower short and lukewarm, not long and hot.
• Pat dry, then moisturize the shaved areas right away.
• Shave every other day if you can, rather than every day.

If you want the legs to keep pace with the rest of you, a tan extender on shaved areas helps even things out. One comes in the take-home kit with Spray Tan+, alongside a tan-safe soap and natural lotions; both options are on the services page.

The short version

Exfoliate, then shave, the day before. Arrive with clean, dry skin and no deodorant, lotion, perfume or makeup. Don’t shave until after your first rinse, and then shave gently.
