Laser Hair Removal vs Waxing vs Shaving

Shaving removes hair at the surface and lasts a day or two. Waxing pulls hair from the root and typically lasts three to six weeks. Laser hair removal damages the follicle itself and, after a full series, can lead to a long-lasting reduction in growth. None is right for everyone: the most suitable choice depends on your hair colour, skin, budget, comfort and how much time you want to spend on hair removal over the years.

How each method works

Shaving cuts the hair where it meets the skin. The follicle is untouched, so hair grows back quickly. Despite a common myth, shaving does not make hair grow back thicker or darker. Regrowth can feel coarser because the cut tip is blunt rather than tapered.

Waxing (along with sugaring and epilating) pulls the whole hair out from the root. It takes longer for a new hair to reach the surface, so smooth skin lasts weeks rather than days. The follicle is not destroyed, and hair returns.

Laser hair removal uses light absorbed by the pigment in the hair to heat and damage the follicle. Treated follicles produce fewer, finer hairs or stop producing hair. It requires several sessions and works only on hair with enough pigment. Our article on how laser hair removal works explains the science.

How long the results last

• Shaving: one to three days, depending on how fast your hair grows.
• Waxing: commonly three to six weeks. Some people notice slightly sparser regrowth after years of regular waxing, though this is not consistent.
• Laser: after a full series, many people have a substantial, long-term reduction. Some regrowth is common, and occasional maintenance sessions may be needed. Results vary from person to person.

Ingrown hairs and bumps

Ingrown hairs happen when a hair curls back or grows sideways into the skin, causing red, sometimes painful bumps. They are especially common in people with curly or coarse hair and in areas like the bikini line, beard area and underarms.

Shaving and waxing can both contribute to ingrown hairs. Shaving leaves a sharp tip that can pierce the skin as it grows. Waxing can distort the follicle or break hairs below the surface.

Because laser reduces the number of hairs growing, it often reduces ingrown hairs and the bumps that come with them. For people with persistent razor bumps (pseudofolliculitis barbae), this can be one of the most meaningful benefits. Severe or infected bumps should still be assessed by a doctor.

Whatever method you use, some habits help reduce ingrown hairs: shaving with a sharp, clean blade in the direction of growth, avoiding pressing hard, gently exfoliating a few times a week, and not picking at bumps, which can lead to infection and dark marks.

Skin irritation and comfort

Shaving is painless when done well, but can cause razor burn, nicks and itching, especially on sensitive skin or with dull blades.

Waxing stings as each strip is removed and can cause redness, small bumps and occasionally bruising, burns from overheated wax, or skin lifting. People using retinoids or certain acne medicines are at higher risk of skin tearing with wax.

Laser feels like a quick snap or hot pinprick, softened by cooling. Redness and bumps are common for a day or two. Less common risks include blisters, burns and pigment changes, particularly in tanned or darker skin if settings are not appropriate.

Time and long-term cost

Shaving costs little per use but adds up in time: minutes several times a week, for years. Waxing needs less frequent effort, but each appointment takes time, and the cycle repeats indefinitely. Hair must also grow out between waxes, which some people find inconvenient.

Laser has a higher upfront cost spread over a series of appointments, followed by occasional maintenance. For some people, the reduced time spent on hair removal over many years makes it worthwhile. For others, especially those with light hair that will not respond, or those who only remove hair occasionally, it is not good value. It is also worth remembering that hormonal changes later in life can bring new growth, so laser rarely means never thinking about hair removal again. Fees for laser are disclosed in full at consultation, and aesthetic treatments are not covered by MSI.

Who each method suits

Shaving suits almost anyone, any hair colour, and anyone who wants a low-commitment option or removes hair only occasionally.

Waxing suits people who want longer smoothness without a series of medical treatments, and those with light or grey hair that laser cannot target. It may not suit people on retinoids, isotretinoin or blood thinners, or those with very sensitive or thin skin.

Laser generally suits people with darker hair who want a long-term reduction and can commit to a series. It is not usually suitable for blond, grey, white or most red hair. It should be postponed during pregnancy, with a tan, with an active infection or cold sore in the area, and after recent isotretinoin. New or rapidly increasing hair growth should be checked by your family doctor first to rule out a hormonal cause.

Switching methods takes some planning. If you choose laser, you will need to stop waxing and plucking for several weeks beforehand; see our guide to preparing for laser hair removal.

Frequently asked questions

Can I combine methods?

Yes, but carefully. During a laser series you can shave between sessions, but you should avoid waxing or plucking the treated areas. Waxing other, untreated areas is fine.

Is electrolysis an option?

Electrolysis destroys individual follicles with an electric current and works on any hair colour. It is slower, since each hair is treated one by one, and is often used for small areas or light hair.

Do home laser devices work the same way?

Home devices use lower energy for safety. Some people find them helpful, but results are generally more modest, and the same precautions about skin tone and eye safety apply.
