What if my hair is too short?

The wax may not grip properly, so the hair snaps at the surface rather than lifting from the root and the result does not last. Aim for about five millimetres, roughly the length of a grain of rice. If you have been shaving, allow two to three weeks of growth before a first wax. Do not trim it yourself on the day either, because uneven length is harder to remove cleanly.

Gently, and the day before rather than the same day. Exfoliating lifts dead skin so the hair is not trapped under it, which is what causes most ingrown hairs. Exfoliating immediately before a wax is counterproductive: it thins the surface layer and makes the wax lift skin rather than only hair. Start again about three days after the appointment, once the follicles have closed.

Should I shower before the appointment?

Yes, a warm shower shortly before helps. It softens the hair, opens the follicles and means the skin is clean when the practitioner arrives, all of which makes the wax grip better and the appointment more comfortable. Skip heavy body lotion or oil afterwards, since a residue stops the wax adhering properly. In Bangkok heat this matters more than it would in a cooler climate, because you are likely to have been sweating.

How to Prepare for Your Wax

Short answer on how to prepare for waxing: let hair grow to about a grain of rice (5mm), exfoliate gently a day before, and arrive with clean, oil-free skin.

What to get right before you book

Hair length

Around 5mm is ideal — long enough for the wax to grip, short enough to stay comfortable. If it’s longer, we can trim.

Skin prep before your wax

Two things, and the timing matters as much as the doing:

Exfoliate gently the day before, which reduces ingrown hairs.
Skip creams, oils and perfume on the day, so the wax adheres properly.

Timing

Booking before a beach day or event? See our pre-beach waxing guide to time it right, and aftercare tips, the aftercare tips for the days after for smooth results.

Ready when you are — book mobile waxing to your hotel or home.

On the day

The full checklist (one page, tick as you go)

Use this the morning of your appointment.

☐ Hair length is 5mm or longer (count from the day you last shaved — most people need 10–14 days of growth for a first Brazilian).
☐ Exfoliated gently 24h ago (a washcloth in the shower is enough — don’t scrub).
☐ No body lotion, oil, fake tan or SPF on the area being waxed.
☐ No perfume or deodorant on underarms if that’s on the list.
☐ Clean cotton underwear or boxers — synthetics trap heat and friction.
☐ A glass of water in advance — hydration helps skin elasticity.
☐ If you are anxious about the pain, say so when you book — the practitioner will talk you through it. Ask a pharmacist before taking anything.

What to skip on the day

Skip these four things on the day of your appointment — each one either irritates the skin before waxing or makes the wax grip badly.

No hot yoga, sauna, gym or beach right before — warm, dilated skin reacts more.
No caffeine right before if you’re anxious — it amplifies pain perception.
No retinols or exfoliating acids (AHA/BHA) on the area for 48 hours before.

If something is not ideal

If your hair is the wrong length

Too short (under 4mm): the wax won’t grip properly. Wait 2–3 more days. Don’t shave in the meantime — it’ll just push the appointment back further.

Too long (over 12mm): we can trim with clippers before the wax, but it’s faster if you trim yourself first. Don’t shave — that’s a reset.

If you have sensitive skin

Skip actives (retinol, AHA, BHA, vitamin C serum) on the area for 5 days before and after. Tell us on WhatsApp — we’ll bring Aloevera wax as the default and have a cooling gel ready post-wax.

Preparation is the same wherever we come to you — the district pages set out arrival times and building access, for example waxing in Asok, where the BTS and MRT interchange lets us commit to a tighter window.

This is one of the full guide index — the rest cover preparation, aftercare, wax types and the safety questions worth asking.
