Types of natural hair extensions: which one to choose
Nais Hair Guide
If you want extensions that stay in, are comfortable and last more than a year, tape-ins are the option we recommend most. If you often wear your hair up and don't want any strip to show, choose SEAMLESS 4K tape-ins, especially at the temples. Keratin gives a strand-by-strand bond, but needs a professional. And if you only want them for a wedding or an event, clip-ins, which you put in and take out yourself, are enough and more budget-friendly.
We have been selecting and processing our own hair since 2007. Most of our customers who started with sewn wefts have switched to tape-ins because of how they are applied and how comfortable they are.

Choose yours
One sentence for each type, so you know in seconds if it's for you.
Tape-ins
If you want fixed extensions for everyday wear, comfortable even for sleeping, that you can reposition many times by changing only the tape.
See tape-ins
SEAMLESS 4K
If you wear your hair up and don't want any strip to show. Combine them with regular tape-ins: SEAMLESS 4K at the sides and regular ones for the rest.
See SEAMLESS 4K
Keratin
If you prefer a strand-by-strand bond and have a trusted professional to apply them.
See keratin
Virgin hair
If you want maximum lifespan, hair that has never been dyed or bleached, or a wavy or curly texture. Dark colors only.
See virgin hair
Clip-ins
If you want them for a wedding, an event or a specific day, and would rather not spend on something designed for everyday wear.
See clip-ins
Sewn weft
If you want a classic, versatile system: it is sewn in, glued in or attached with beads, or you can make it removable by sewing clips onto it.
See sewn weftFrequently asked questions
The questions we get asked most when choosing.
Tape-ins or keratin?
You can apply tape-ins yourself, with help, in about 30-45 minutes, and they are repositioned by changing only the tape. Keratin needs a professional (1 to 3 hours) and is repositioned with new keratin. Both last 12 to 24 months and are moved up every 2-3 months.
What is the difference between regular tape-ins and SEAMLESS 4K?
How they attach. With SEAMLESS 4K the hair sits on a thin base that mimics the skin of the scalp, so the strip doesn't show even when you wear your hair up. They are applied and reused just like the regular ones.
Which ones last longest?
Virgin hair: 1 to 3 years, and some customers have worn it for up to 5. The premium ones (tape-ins, SEAMLESS 4K and keratin) last 12 to 24 months, and the economy ones (clip-ins and sewn weft), 6 to 12 months.
Which extensions should I wear for a wedding or an event?
Clip-ins: you put them in and take them out, you can apply them yourself in seconds, and they are the most budget-friendly. For a one-off occasion you don't need the premium range.
How many extensions do I need for a full head?
With tape-ins or SEAMLESS 4K: 2 packs for natural volume, 3 for XL volume and 4 for spectacular XXL volume (from 300 to 800 € in total). With clip-ins, 1 set is enough. With sewn weft, 1 pack of 100 g, or 2 for spectacular XXL volume.
Can I combine several types?
Yes. The most common combination is regular tape-ins with SEAMLESS 4K at the temples, so no strip shows when you wear your hair up.
