Frequently asked questions

What is Laser Hair Removal?

Laser hair removal is the reduction of dark hair using light energy.

How many treatments will I need and how often?

Most clients achieve a great result in x6 sessions. You can achieve up to a 90% reduction in dark hair but some finer, lighter hairs will not respond to treatment. Certain factors such as hormonal influences may mean more sessions are required. This is discussed on consultation. An example of this is PCOS [Polycycstic Ovarian Syndrome] as it can stimulate new hair growth. After the initial x6 sessions, some clients may have the odd top-up/maintenance session a year to keep their great result. Facial areas are treated every 4-6 weeks and body areas every 6-8 weeks.

Can I shave between treatments?

Yes! Please do not wax, pluck, dye or epilate the hair as avoiding any root stimulation gives a better result. Treatment is over clean-shaven skin, best shaved the evening before your next session. Unlike waxing, you do not need to grow your hair in-between sessions.

How do I prepare for my Laser Hair Removal treatment?

A gentle, close/wet shave the evening before treatment means your skin is far less irritated to receive treatment the next day. Especially for those of us who may suffer from shaving rashes. Exfoliating your skin gently between sessions can also give better results as less dead skin is built up, allowing even better penetration of the laser energy to its target.

Why is Laser Hair Removal more expensive than waxing?

There are a few reasons why laser treatment is more of a premium than waxing and other hair removal methods: * Laser is a permanent reduction of unwanted hair. * You will save time and money on future hair removal methods. * Your treatment provider should be regulated in Wales to provide this treatment. This comes with increased overheads and experience. * The laser at OneYou is medical grade and an industry leader for this technology. It's also why the machine is so big! Essentially, an unwritten industry rule is the bigger the system, typically the more powerful. Hence why at-home retail versions are not very successful, they simply don't have the same power. * Laser is also more expensive than IPL as it is a more targetted treatment and therefore a more expensive system both to purchase and maintain. This is often the reason why intense pulsed light (IPL), is more readily available. That doesn't mean IPL doesn't work, but Laser is more direct, therefore you get better results, quicker.

Do you offer discounts on courses?

Yes! All courses are at least 10% less expensive than buying the treatments individually. Some popular treatment areas are packaged as combinations too such as lip & chin or underarm & hollywood bikini. That way you save even more. OneYou also offers a price-match guarantee against any registered clinic pricing in the same area. Look out for special offers too!

Does Laser Hair Removal hurt?

The best way LHR is described is like the warm flick of an elastic band. Most clients say it is more comfortable than waxing. Some parts of treatment you may not even feel but everyone is different. A cryo blower simultaneously blows cold air while you have treatment. This can be turned up and down as per your individual tolerance.

Is Laser Hair Removal safe?

What type of laser does OneYou use?

OneYou uses the medical-grade Cynosure Elite +. It is comprised of two lasers, allowing the safe treatment of all skin-types.

Why do I need a Consultation and patch test?

A medical history is taken to ensure suitability for treatment. Your hair and skin is assessed and a patch test allows the best treatment setting to be used for your first laser hair removal session while keeping your skin safe.

Why are Consultations booked with a deposit?

Deposits are taken to protect the diary. If you give sufficient notice to cancel/rearrange or are unsuitable for treatment following a consultation, the deposit is fully refundable. If you proceed with treatment, it comes off the cost.

Where is OneYou based?

OneYou is based within The Doll House Hair & Beauty Boutique at 451 Cowbridge Road East, Cardiff, CF5 1JH. The Doll House provides a beautiful hair and beauty salon with a range of treatments and a professional, friendly team. Take a look at what they do at

Will the treated hair fall out straight away?

No - it usually takes two weeks after treatment for the hair to fall out. You won't really notice until you see the area has gone 'patchy' and requires less maintenance.

Will Laser Hair Removal work on my hair type?

Laser works best on dark hair as light energy is attracted to dark pigment. Sadly, it does not work on blonde, red, white or grey hair.

Why do you offer courses of 3 when other clinics offer courses of 6?

OneYou starts course discounting at just x3 sessions as we'd rather offer discont without large payments upfront. As we know you'll likely need a second course of x3 treatments, it will be honoured at the purchase price of your first course if purchased within 12 months of each other. If you purchased all x6 treatments upfront you're paying for 6-9 months worth of treatment in advance, this way, you can spread the cost without paying so much upfront or taking out a finance agreement. It also means if you have had treatment elsewhere previously, you can benefit from course discount without being locked into a minimum of x6 more sessions.
