Welcome to our Lazarou Duke Street Salon aka Lazarou Cardiff Castle! 

We are a team of dedicated hair stylists and live by our motto: Your Hair, our Care! 

You can find us opposite Cardiff Castle, directly at the corner of Duke Street Arcade - one of Cardiff´s many beautiful Arcades. As family-run, independent local business we absolutely love our location and the place it gives us in Cardiff´s city centre and its community.

We are passionate about all things hair | Regular Hair Appointments

Hair is constantly exposed to external forces -  changing temperatures, heat styling devices or styling products, for example, cause hair damage, leaving your hair look dull.

Regular haircuts and revitalising hair pampering sessions are important to keep your hair healthy, shiny and strong. We recommend 6-8 weeks between your haircut appointments.

Plus a blow-dry, haircut or nourishing dual sense mask are speedy appointments that fit any schedule and will do wonders to your hairs health.

We love all things colour  | Hair Colouring Appointments

Balayage, Highlights, Lowlights, Root Colour, Bleach, Global Hair colour all-over, Face Frames or Money Pieces (trend alert!), the choice is yours! On top of that you can book our colour refreshes in between your colour appointment to keep your hair colour vibrant, shiny and full of life.

Have you ever tried creating that latest hair colour trend at home and it went terribly wrong? We also offer colour correction appointments - read here an example of one of our colour correction appointments - to save your DIY box dye project.

We like to go the extra mile | Hair Extensions

From short to long and voluminous: Real Human Hair Extensions found their way into our salon and into our hearts. Incredible hair transformations from thin strands to voluminous and long hair, all is possible now. We use weft weaves and tape extensions in our salon, which we adapt to your hair needs.

It is an exciting journey - from the initial consultation, hair colour adaptation, to the extension fitting appointment. Especially important is the extension aftercare at home and the maintenance appointments in our salon to keep your hair extensions looking their best. Our extension specialists will be here for you along your whole hair extension journey.

We are here for you right from the start | Free Consultation

Are you overwhelmed by the choice or end up asking yourself:

What hair colour suits me best?

Which haircut is best for my face shape?

Or basic questions like which hair type do I have?

And which hair products should I use?

Book in for a free consultation (via our online booking system here) with one of our stylists and let us find the right hair colour to fits your skin tone, discuss your personal hair goals or if the the latest hair trend would suit you. We are here to discuss any hair-related question you might have.

Your health always comes first

Please book your patch test/skin allergy test before your first colour appointment at our salon. We need to make sure that you will not have any allergic reaction to the ammonia in our colours. This needs to be done at least 48h before your hair colour appointment, is valid for 6 months and can ideally be done with one of our free consultations. Good news is: We do have ammonia free hair colour and will talk you through all options.

We are advocates for: Self-care is the ultimate form of self-love. Especially when times are uncertain, focusing on your own wellbeing is a great coping mechanism. Whether a nourishing and hair strengthening dual senses hair mask as pick-me-up or a Sunday pampering session, we are here to take care of you and your hair.

We use the safest application methods for your hair extensions. All our extension technicians are fully trained in providing the service and will guide you through your entire extension experience:

If you are happy to go ahead with the appointment we will order your hair extensions directly after your consultation.

Let’s book your ideal hair appointment: We operate from Monday to Saturday and one of our extension specialists is always in the salon to ensure maximum availability.

Please be aware that we can only book your hair extension appointments after the initial consultation as we then know how long your appointment will take and can allocate the right time slot for you.

The heart of the journey,  ie. your hair extension appointment: Long, luscious locks in the making!

The right aftercare and maintenance of your extensions are a key element to keep your hair strands looking healthy and shiny. We will talk you through all there is to know plus give you a take-home leaflet with all important steps.

Following your extension appointment we will give you a complimentary aftercare set worth £35 consisting of shampoo and conditioner. Our sulphate-free range is full of antioxidants that protect your hair against environmental pollutants.

What kind of hair do you use for your hair extensions at Lazarou Duke Street?
We use 100% human remy hair, which is double-drawn.

a. What is remy hair?

Remy hair is considered the finest quality of human hair: The cuticles are kept intact which allows our technicians to align the hair cuticle in the hairs natural direction achieving a natural look and feel of the extensions. 
b. What is the difference between single-drawn and double-drawn extensions?

Extensions are strands of hair sewn into wefts. Single-drawn extensions are thicker on the top and thin out towards the end.

Double drawn extensions are fuller, all hair is nearly the same length and the same thickness from the root to the tip of the extension strand to achieve a full, volumous body of hair.

What are tape hair extensions?
Tape hair extensions are made up of small wefts of hair that are attached to a tape strip. The tape is then applied to the natural hair, sandwiching the weft between two strips of adhesive tape. This method creates secure and natural-looking extensions that lay flat against the scalp. Tape hair extensions can be styled and washed like natural hair.

What are nano hair extensions?
Nano hair extensions use tiny, bead-like rings that are used to attach individual strands of hair to the natural hair. Nano hair extensions are made using a special technology that allows for a very thin and lightweight extension strand, which means they are easy on the natural hair while creating a natural look.

How long will my extensions last?

Our double-drawn remy hair extensions have a life-span of up to 12-18 months depending on the appropriate aftercare and maintenance.

The right aftercare is as much a commitment of our technician to fit your extensions with utmost care and expertise as well as your commitment to look after them outside the salon.

How much will my hair extensions cost?

Our extension service is unique to every client as we adept the extensions to fit your natural hair and lifestyle. The pricing reflects that and depends on the amount of hair extensions we will order for you, the time it takes to fit them and the colour matching.



Our team of hair extensions technicians will work with you to choose the perfect styles and colours to complement your natural hair. Book now and take the first step to your best hair yet!
