Most people need a course of laser hair removal sessions rather than a single appointment, and many are advised to plan for around six treatments spaced several weeks apart, which is why we price each area per session and as a course of 6. Your exact number depends on your hair colour, skin tone, the area treated and your hormones, so six is a starting point, not a fixed rule.
Why one session is never enough
Laser hair removal works by sending light energy into the pigment of the hair, which converts to heat and damages the follicle that produces it. The catch is that only follicles in their active growth phase respond well. At any moment, a large share of your hairs are resting or shedding instead, and those follicles are largely unaffected by the treatment you have that day.
Hair moves through three broad stages:
- Growth (anagen): the hair is attached to the follicle and full of pigment. This is when laser has the most effect.
- Transition (catagen): the hair detaches and growth slows.
- Rest (telogen): the old hair sheds and the follicle waits before starting again.
Each session catches a different group of follicles in the growth phase. Spacing appointments allows a new wave to come through, so the course gradually works its way across the whole area.
What changes the number of laser hair removal sessions you need
Two people treating the same area can have very different journeys. The main factors are:
- Contrast between hair and skin. Dark hair on lighter skin usually responds most readily. Very fair, red, grey or white hair has little pigment for the laser to target, so it may respond poorly or not at all.
- Hair thickness. Coarse hair often reduces noticeably early on; fine, downy hair can be slower.
- Treatment area. Facial hair is often strongly influenced by hormones and may need more sessions and ongoing top-ups than areas such as the legs or underarms.
- Hormones. Conditions such as polycystic ovary syndrome, menopause, pregnancy and some medicines can stimulate new hair growth, which can extend a course.
- Consistency. Missing appointments or leaving long gaps lets the growth cycle reset, so sticking to the plan matters.
- What you do between sessions. Waxing, threading or epilating removes the root the laser needs, which can make sessions less effective.
How far apart should sessions be?
Sessions are usually spaced several weeks apart. Areas where hair grows quickly, such as the face, are often treated at shorter intervals than slower-growing areas like the legs or back. Your practitioner sets the timing for each area, and the plan may be adjusted as your regrowth changes.
Booking sooner than recommended does not speed things up. It simply means treating follicles that have not yet re-entered the growth phase.
What you might notice across a course
| Stage | What many people notice |
|---|---|
| Sessions 1 to 2 | Treated hairs may shed over the following couple of weeks. Regrowth can look patchy, which is normal. |
| Sessions 3 to 4 | Regrowth is often finer, lighter and slower, with smoother patches appearing. |
| Sessions 5 to 6 | Many people see a clear reduction and shave far less often. |
| After the course | Occasional maintenance sessions may be suggested if hormones or new hairs cause some regrowth. |
Everyone responds differently, so treat this as a rough guide. Our before and after laser hair removal guide explains what is normal straight after treatment and how to care for your skin between visits.

Maintenance after your course
Laser hair removal offers long-term reduction, not a promise that every hair will never return. Some follicles survive treatment and produce finer hairs, and hormonal changes can wake up new ones years later. Many people find an occasional top-up session keeps things smooth. It helps to view the first course as the main work and maintenance as light upkeep when you need it.
Who should wait, and who may not be suitable
Laser is not right for everyone at every moment. You may be asked to wait, or advised against treatment, if you:
- are pregnant or breastfeeding
- have a recent tan, sunburn or fake tan on the area
- take medicines that make skin more sensitive to light, or have recently taken certain acne tablets
- have an active skin infection, cold sore, open wound or flare of eczema in the area
- have a history of keloid scarring or certain light-triggered conditions
- have mainly white, grey or very fair hair in the area you want treated
Mild redness and raised follicles that look a little like goosebumps are common for a few hours afterwards. Contact the clinic if you notice blistering, crusting, darker or lighter patches, or redness that is not settling. If you are unsure whether laser suits your skin or hair, a skin consultation with our skin scanner is a useful first step before committing to a course.
Frequently asked questions
Will I see a difference after one session?
Some people notice shedding and slightly slower regrowth after the first session, but meaningful reduction usually builds over several treatments.
Why is hair still growing after three sessions?
This is common. Follicles that were resting during earlier sessions are now growing and need treating. Regrowth is often finer than before.
Does the face need more sessions than the legs?
Often, yes. Facial hair is closely linked to hormones, so it may need more sessions and occasional maintenance.
Is a course of 6 enough for everyone?
Not always. Many people are happy after six, while others with hormonal hair growth or finer hair may benefit from additional sessions. Your progress is reviewed as you go.
