Tape-in vs keratin - what suits your hair?
You want fuller lengths, soft movement, and a result that feels like your own hair - but choosing between tape in vs keratin can feel difficult. Both methods can provide a beautiful, natural result, but they suit different hair types, routines, and preferences. The best choice is not always the method that lasts the longest, but the one that feels comfortable, looks seamless, and works for your everyday life.
Tape in vs keratin - the main difference
Tape-ins are attached by placing thin hair sections between two adhesive tape attachments. The attachments lie flat against the head and distribute the hair in wider, thin sections. The result is often soft, discreet, and flexible, especially when the hair is well colour-matched and the amount is adapted to your own hair.
Keratin extensions consist of smaller hair strands with a keratin attachment at the top. A trained hairdresser attaches the strands close to the scalp, section by section. Since each strand is placed individually, it is possible to create a highly customised distribution - perfect when you want to build fullness in selected areas or create a natural transition in a layered haircut.
Both methods use genuine Remy hair when you want a soft feel and a result that moves naturally. The main difference is how the attachments feel, how they are applied, and what type of flexibility you want.
When tape-ins are the right choice
Tape-ins are a favourite for anyone who likes a smooth, flexible result without lots of small attachments. The thin tape strips lie close to the head, making them particularly beautiful in straight hair or with a soft blow-dry when you want the lengths to look even and natural.
The method often suits those with normal to thick hair who want to create more volume, length, or both. If you lead an active life but want to be able to style your hair as usual - curl it, blow-dry it, and put it up - tape-ins can be a reliable option. You only need to consider the placement when creating high, tight updos, so that the attachments remain well hidden.
A major advantage is reusability. When the tape has grown out, a hairdresser can remove the hair, replace the tape, and reattach the same lengths if the quality is still good. This makes tape-ins a great choice for anyone who sees extensions as a recurring part of their hair look and wants to care for the investment over time.
Tape-ins usually need to be moved up after approximately 6-8 weeks, depending on how quickly your hair grows and how well you follow the care instructions. If you wait too long, the attachments may become more visible and the hair more difficult to manage at the roots.
Tape-ins may suit you if you want
A flat and discreet attachment, the option to reuse the hair, and relatively quick application at the hairdresser. The method is also ideal when the goal is a soft, even overall look rather than a change in a few individual areas.
When keratin is the right choice
Keratin is for anyone who wants maximum freedom in placement. The small strands can be adapted to where your own hair needs the most support, for example around the face, at the sides, or in a haircut where certain layers feel thin. This gives the hairdresser the opportunity to create a result that truly follows your natural hair growth.
The attachments are small and discreet, making keratin a beautiful option if you often wear your hair up or want to vary between curls, straight styling, and braids. When applied correctly, each strand can blend in so well that the hair feels completely like your own.
Keratin usually remains in place for approximately 3-5 months. Exact longevity is affected by your hair growth, how you wash your hair, your styling habits, and how carefully you look after it at home. Unlike tape-ins, keratin strands are not moved up. Instead, they are removed by a hairdresser when it is time, and if you want to continue wearing extensions, new hair or new attachments are applied.
Application often takes longer than tape-ins because each strand is applied separately. For many people, the time is well worth it precisely because the result is so personal. If you want to fill out small areas without adding a lot of hair all over your head, keratin is often the more precise choice.
Keratin may suit you if you want
Small, individual attachments, great freedom in placement, and a result that can easily be adapted to your haircut. It is also a great choice if you do not want to schedule maintenance as often as with tape-ins.
What suits thin, fine, or thick hair?
If you have fine hair, extensions always need to be adapted with extra care. Too much hair or incorrectly placed attachments can feel heavy, regardless of the method. Keratin can be particularly good for fine hair when the hairdresser uses small sections and builds volume where it is needed without overloading the hair. Tape-ins can also work very well, but require the right amount and carefully considered placement so that the attachments do not show through.
If you have normal to thick hair, both methods often work excellently. Tape-ins can provide plenty of fullness efficiently, while keratin makes it possible to blend in the lengths in greater detail. If your hair is very thick, you often need enough extensions for the transition between your own hair and the lengths to be soft. Too little hair can make the result look divided, no matter how good the quality is.
Your natural haircut also plays a role. Straight, one-length hair is often easy to extend with tape-ins. If you have shorter layers, layered sides, or want to create a completely invisible transition around the face, keratin can offer more control.
Care that keeps the hair beautiful
Extensions should feel like a luxury in everyday life, not a project. But a little proper care makes a big difference to both longevity and that soft, freshly washed feeling. Brush your hair gently every day with an extensions brush and hold the attachments in place while detangling the lengths. Always start at the ends and work your way upwards.
Wash your hair with a focus on the scalp and let the shampoo rinse through the lengths instead of rubbing them. Conditioner and hair masks belong on the lengths, but not directly on tape attachments or keratin attachments. Products containing a lot of oil near the attachments can affect the tape's grip, while residue around any type of attachment can make the hair feel less fresh.
It is a good idea to sleep with your hair in a loose braid or low ponytail, and never go to bed with wet hair. Heat protection is essential when you blow-dry or style. Real hair needs care just like your own hair, especially if you want to maintain its shine and flexibility for a long time.
Quality makes more difference than you might think
The method is important, but hair quality determines much of how the result feels after a few weeks. Hair with an intact cuticle layer often stays softer, tangles less, and retains its natural shine for longer. It is an investment in the feeling of being able to run your fingers through the lengths without encountering dry, coarse sections.
At B's Extensions, both Original and Luxury are available in genuine Remy hair. Original is an affordable option for anyone who wants a beautiful result, while Luxury has an intact cuticle layer for an even softer feel and longer-lasting quality. Whichever quality you choose, the colour, length, and amount need to work together with your own hair for the overall look to feel natural.
Choose based on your everyday life, not just the picture you saved
If you want to be able to reuse the hair and appreciate flat attachments, tape-ins may feel exactly right. If you dream of small, flexible attachments and customised placement, keratin may be the method that makes you feel like your very best self. There is no universally best option - only what suits your hair type, budget, styling routine, and how often you want to return to the hairdresser.
If you are unsure, start by considering your own hair rather than how much length you want. An honest assessment of colour, density, and wear will always produce a more beautiful result. Once the method and hair have been chosen correctly, extensions should not feel like something you need to hide or think about - they should simply make you feel a little more like yourself.
