Hair clipper; not just another trimmer;

Since hair clippers and hair trimmers have a lot in common, they are mostly confused by people as the same things. Although, this is hugely incorrect. A hair trimmer and a hair clipper are very different when it comes to their functions and what they can do.

Talking about differences, a hair clipper is used to cut longer hair and comes with different attachments, while a hair trimmer is used frequently for shorter or finer hairs. The purpose of a hair clipper and its design align together and give very short hair to the person using it. A hair clipper prepares the hair for a smoother finish and a final cut. A trimmer works on fine details and shorter hair lengths. Trimmers have an increased ability to cut the hair very close to the skin, as compared to hair clippers, that give you shorter hair lengths but not as short or close-to-the-skin as a hair trimmer.

Now that you know about the difference between a hair clipper and a hair trimmer, let us move on further. We will now discuss different ‘haircut numbers’ and how can they influence your hairstyles. Haircut number is very important and one should be aware of their details in order to use a hair trimmer more efficiently and accurately. These haircut numbers are associated to various clipper guard sizes. Baffled? We know! Just stay tuned to find out what a clipper guard size is and how is it related to various haircut numbers. I have mentioned many clipper guard sizes examples.

Hair Clipper Sizes and Haircut Numbers

Different hair clipper sizes are also termed as different ‘clipper guard’ sizes. Hair clippers come with various clipper guard sizes. These guard sizes determine what amount of hair will be cut, and what hairstyle will be formed as a result. Each guard size comes with a number etched on it. These numbers represent the amount of hair that will be left on one’s head after the grooming session using that specifically numbered guard.

Mostly, the larger the number etched on the clipper guard, the longer the haircut. Most of the hair clippers, provide 8 guards that can give you different hair lengths and different hairstyles.

To make it clearer, let us give you an example. So, if you go to a barber and ask for a ‘number 2’ haircut, it means that the clipper guard with the number ‘2’ etched on it will be attached to the clipper. Now, in order to find out which haircut number can cut how much hair and leave what amount of hair on your head, let us explain further below;
