Sew-in extensions, also known as weaving, are one of the most tried-and-tested hair extension methods. Your own hair is braided in thin rows close to the scalp, and a hair weft is sewn onto the braid with a needle and thread. No glue, no heat and no chemicals touch your own hair.
What you need to know before your first time
Your own hair needs to be long enough to braid. In practice, about shoulder length or just below. If it is shorter, we would rather look at another method.
You will feel the rows for the first day. Rather like after a tight ponytail. The feeling fades once your scalp gets used to it. It should never hurt – tell us straight away if it does.
You need to set aside time. A full installation takes longer than tape or clip-on extensions, because each row is braided and sewn by hand.
How the treatment works
We start with colour matching in daylight and decide where the rows should go, based on your hair growth and how you usually wear your hair. If you always wear a centre parting, the rows are placed differently than if you often wear a ponytail.
Then your hair is washed and braided, and the hair weft is sewn in. Finally, we cut the extensions together with your own hair so the transition disappears. You leave with your hair finished.
Lifespan and move-up
The hair weft stays in for months and is moved up every two to three months as your own hair grows. The same hair can be reused several times, which makes the method cheaper over time than it looks at the first order.
Aftercare
Wash with a sulphate-free shampoo, massage your scalp between the rows and blow-dry the braids completely. Brush from the ends upwards with a soft extension brush, and hold the hair at the base so you don't pull on the rows. Braid your hair loosely at night.
Frequently asked questions
Does it hurt?
No. The braids should feel secure but never painful. If you have a sensitive scalp, let us know and we will braid more loosely.
Can I style my hair as usual?
Yes. Human hair can be straightened, curled and blow-dried. Use a heat protectant and stick to low or medium heat.
How much hair do I need?
It depends on the thickness of your own hair and the length you want. We assess this at the free consultation.
