An InkLabs semi-permanent tattoo adheres best to smooth skin, with no visible hair on the chosen area, because the film needs to stay in continuous contact with the skin during the water step. If you’re wearing the design on a hairy area — your forearm, calf or even wrist — the simplest option is to remove the hair beforehand by shaving, using an epilator or waxing, then wait for your skin to settle before applying the tattoo. How long you wait depends on the method you choose: a few hours after shaving, a day or more after using an epilator or waxing.
In short, before we get into the details:
- Hair breaks the contact between the film and the skin, so the design edges come out blurry and the tattoo peels off faster precisely in the hairy areas.
- Shaving is the quickest option when you’re applying the tattoo that same day, but the hair becomes visible again within one to three days.
- Using an epilator or waxing keeps the skin smooth for three to four weeks, but the follicles remain sensitive for a while, so it makes sense to apply the tattoo the next day, not immediately afterwards.
- If your skin reacts easily to using an epilator or waxing, the patch test before application shows whether that area tolerates the tattoo well.
What happens to hair beneath a semi-permanent tattoo
Applying an InkLabs semi-permanent tattoo involves exfoliating the area, drying the skin completely, then pressing down the film and wetting it for about a minute before peeling off the backing paper; the colour reaches its final shade in about 24 hours, and the design is made to last for up to around 15 days. Throughout this time, the ink transfers only where the film touches the skin directly. Even a fine hair lifts the film a few millimetres above the skin at that point, and the ink doesn’t transfer fully to the skin there.
In practice, this means that if you skip preparing the hair, you risk blurry edges on fine lines, small gaps in the outline and a tattoo that lifts sooner precisely in the hairy area, even if the rest of the design lasts well. The InkLabs application instructions list areas with excessive hair among the areas not recommended, along with irritated or damaged skin, scars, moles and stretch marks.
If you’re looking for the full application steps, from exfoliating to peeling off the paper, the guide to applying a temporary tattoo at home covers them one by one; here, we’re focusing only on preparing the hair and skin beforehand.
If your design has smudged or faded unevenly for reasons other than hair in the area, the common causes of a smudged semi-permanent tattoo cover the other possible scenarios too.
Shaving, using an epilator or waxing: what each method does to your skin
The three hair-removal methods don’t affect the skin in the same way, and the difference matters both for how soon you can apply the tattoo and for how long the area stays smooth.
Shaving
Shaving cuts the hair at the surface of the skin without touching the root, which is why regrowth becomes visible within one to three days (source: Cleveland Clinic). Razor irritation depends more on technique than on the method itself: dermatologists recommend shaving in the direction of hair growth and softening the hair beforehand, for example at the end of a shower or with a warm compress, as well as using a moisturising shaving cream to reduce the risk of irritation. If left untreated, repeated razor bumps can leave lasting marks over time, so they’re worth paying attention to even if the area seems unremarkable (source: American Academy of Dermatology).
Using an epilator
An epilator pulls the hair out from the root, so the skin stays smooth for around three to four weeks, similar to waxing. Because the follicle remains temporarily open, the skin is more reactive immediately after epilating, which sometimes leads to redness or small, short-lived bumps. Compared with waxing, epilating tends to carry a somewhat lower risk of skin complications, but that difference doesn’t remove the need to let the skin settle before doing anything else to the area, including applying a tattoo (source: Healthline).
Waxing
Waxing removes the hair from the root, just like an epilator, with a similar three to four weeks of smooth skin. However, open follicles leave the skin vulnerable for a while to redness, irritation, small breakouts or ingrown hairs, and dermatologists recommend waiting at least 24 hours before doing anything else abrasive to that area (source: Healthline).
How long to let your skin settle before applying the tattoo
The practical rule is simple: wait until any redness, sensitivity or small visible bumps from using an epilator or waxing have settled instead of applying the tattoo immediately afterwards. Skin that’s just been epilated or waxed is the most reactive of the three cases because the follicles remain open for a while, and dermatologists recommend leaving at least a full day before any additional treatment on that area. This waiting period fits exactly with InkLabs’ restriction against applying the tattoo to irritated or damaged skin: for a few hours, skin that’s just been epilated or waxed may fall into both categories at once.
After shaving, the wait is much shorter, usually a few hours, just long enough for any stinging to go away. If the area is still sensitive to the touch or you notice razor bumps, wait for them to subside before continuing. And if your skin often reacts to using an epilator or waxing with persistent redness or itching, the patch test before applying the tattoo gives you a clear picture; if itching or redness does appear after the tattoo has already been applied, what you can do in that case is covered separately.
How your choice affects how long the tattoo lasts
The InkLabs instructions note that designs applied to joints, areas with excessive hair, dry skin or areas washed frequently, such as wrists or hands, generally fade faster than those on smooth, flat and moisturised skin. This means your choice of hair-removal method matters for how long the tattoo lasts, not just for how it looks on the first day.
Because shaved hair becomes visible again within one to three days, while the tattoo is made to last for up to about 15 days, the hair may start to show long before the design itself fades, especially in areas with thicker hair. Using an epilator or waxing gives you a period of smooth skin that’s much closer to the tattoo’s wear time, which is a practical reason to plan one or two days ahead instead of shaving on the morning you apply it. For the full list of factors that shorten or extend the life of a semi-permanent tattoo, the article dedicated to this topic goes into more detail beyond hair removal.
Which option makes sense for your area
The right method depends less on your usual preference and more on how much time you have before application and how important it is to you that the skin stays smooth for as long as you wear the tattoo.
- If you’re applying the tattoo that same day, a careful shave a few hours beforehand is usually the least disruptive option, because the skin has time to settle by evening.
- If you’re planning around an event and want your skin to stay smooth for as much of the time you wear the tattoo as possible, using an epilator or waxing a day or two beforehand is a better match for the wear time.
- Whatever the method, a smooth, flat and moisturised area remains the choice most likely to give you sharp edges and longer wear, exactly as the product instructions indicate.
Once you’ve decided how to prepare the area, the next step is to choose a design that suits that spot. The Semi-permanent tattoos collection brings together all the available designs, from fine outlines to larger drawings, so you can compare which one suits the area and the occasion you’re getting ready for.
