How does the tip design of the dense-tooth lice comb avoid scratching the scalp?

The tips of the teeth are rounded and polished
When designing a dense-tooth lice comb, in order to avoid scratching the scalp, the tips of the teeth are usually rounded and polished. Through mechanical or manual polishing, the tip of each comb tooth is slightly arc-shaped or bead-shaped to reduce the sharpness. In this way, during the combing process, the comb teeth can smoothly contact the scalp and are not easy to cause scratches or stings. The rounded and polished comb teeth can not only remove lice, but also play a certain massage role, helping to relieve scalp tension.

Tiny ball head design at the tip of the teeth
In order to further reduce the risk of scratches, some dense-tooth lice combs use a design that adds a tiny ball head at the tip of the teeth. After the metal or plastic comb teeth are formed or processed, the tooth tips are thickened or welded with a tiny spherical structure to increase the contact surface. The ball head can more evenly disperse the pressure exerted by the comb teeth on the scalp, reduce local pressure, and avoid scratching or puncturing the scalp due to excessive local force during combing. This type of design is more common when used by children and sensitive scalps.

Improved flexibility of comb teeth
The material selection of the teeth of a dense-tooth lice removal comb is also an important factor in avoiding scratching the scalp. The use of stainless steel wire, engineering plastics or high-toughness alloys with good flexibility can make the comb teeth moderately elastic when combing, and can bend slightly according to the contour of the head, reducing the hard friction between the comb teeth and the scalp. The improved flexibility makes the lice removal comb have sufficient strength to remove lice and eggs, and will not cause scalp damage due to excessive rigidity.

Optimization of the density and spacing of comb teeth arrangement
In order to balance the effect and safety of lice removal, the dense-tooth lice removal comb has been optimized in the tooth pitch design. Too small tooth pitch is easy to get stuck in the hair, increasing the pulling feeling; too large tooth pitch will result in insufficient lice removal effect. Therefore, a reasonable tooth pitch can not only effectively clamp lice and eggs, but also reduce scalp discomfort caused by hair entanglement and pulling. At the same time, the comb teeth are arranged neatly and consistently to avoid local tooth tips protruding to prevent individual tooth tips from scratching the scalp. Some products will have a micro-arc design for the transition from the root to the tip of the tooth to make the overall touch of the comb teeth smoother.

Surface coating and process improvement
In order to further reduce the friction coefficient between the comb teeth and the scalp, some dense-tooth lice combs have added protective coatings or lubrication treatments on the surface of the comb teeth. For example, stainless steel comb teeth are treated with electroplating or anti-rust coating processes to make the surface smoother; plastic comb teeth are polished or coated with antistatic agents to reduce friction and static adsorption during use. These treatments not only improve the combing experience, but also indirectly reduce the risk of scratching the scalp.

Uniform height design of comb tooth ends
In the production of dense-tooth lice combs, strictly controlling the consistency of the height of the comb tooth ends is also an important detail to avoid scratches. If the height of the comb tooth ends is inconsistent, individual tooth tips will be overloaded or protruding during use, which can easily irritate the scalp. Therefore, high-quality lice combs will pass the inspection process after production to ensure that the height of each comb tooth end is uniform and neatly arranged. This not only improves the efficiency of lice removal, but also reduces the risk of scratches.

Use with correct operating techniques
In addition to the design improvements of the product itself, correct usage techniques are also an important guarantee to prevent scratching the scalp. When combing, move slowly from the root to the tip of the hair to avoid excessive force or pulling the hair. It is recommended to use a lice comb after wetting the hair, which can reduce hair tangles and reduce the traction on the scalp. In addition, if necessary, you can use a conditioner to help the comb teeth slide smoothly through the hair, further reducing the possibility of scalp damage.

Check the comb teeth regularly
After using the dense-toothed lice comb for a period of time, some of the comb teeth may be worn, deformed or broken due to frequent cleaning, falling or long-term use. These damaged parts may form sharp edges, increasing the risk of scratching the scalp during use. Therefore, the overall condition of the comb should be checked regularly, and the comb teeth should be replaced in time if they are damaged to ensure safe use.

Design differences for applicable groups
The tooth tip design of the dense-toothed lice comb is also different in products for different groups. Children's special lice combs usually have rounder tooth tips and more reasonable tooth spacing to adapt to children's delicate scalp; adult lice combs may have tighter tooth spacing to enhance the lice removal effect while ensuring safety. For patients with sensitive scalps or scalp diseases, some lice removal combs will have more detailed tooth tip design and material selection to reduce discomfort.
