Is it good to have a mole in the hair

Moles can appear all over the human body, not just in one place. They can appear in many places, and the frequency is relatively high. Some people are born with this condition, while others are due to frequent exposure to ultraviolet rays. In fact, we may also have moles on our scalp, but they cannot be found because they are covered by hair, so we don't need to worry too much about it.

What is a mole? What is a mole?

A mole is a localized abnormality of skin pigmentation that can be present at birth or acquired later in life. A healthy person usually has 15 to 20 moles on their skin. Most of these moles are benign and do not require treatment. But some moles grow on the face and affect the appearance, and different methods can be used to remove them. The commonly used methods of mole removal are as follows: laser method, freezing method, electrocautery method, spot removal machine method and chemical agent method.

A mole is a localized skin pigment abnormality.

Black hairy nevus is a type of pigmented nevus. It often attracts special attention because of its local blackening, rough and raised skin, and hard short hairs. Moles occurring in parts of the body that are prone to friction or injury should be taken seriously. For example, if the mole grows rapidly, becomes lighter or darker in color, the short hair on the mole falls off, the area around the mole turns red, bloodshot can be seen, the surface has ulcers and scabs, or even ulcers that do not heal for a long time are formed. Swollen lymph nodes nearby, or the appearance of small satellite moles around the large mole, all indicate that the mole has a tendency to become malignant. You should go to the hospital to ask a dermatologist or surgeon for diagnosis so that timely treatment can be provided. For the treatment of black hairy nevus, small nevus with a diameter of less than 0.5 cm can be cauterized with laser or high-frequency electric knife. The advantages are simple operation, less damage to normal tissue, and small scars after healing; the disadvantages are that it is difficult to retain nevus tissue for pathological examination and it is not easy to remove it completely. There are also methods of mole removal such as freezing and chemical corrosion, but they are not suitable because of the side effects of incomplete removal and stimulation of malignant transformation of mole cells. The above shortcomings can be compensated by using trephine to remove the nevus. Use a piercing drill that is 0.2 cm larger than the diameter of the mole to drill the entire mole after local skin anesthesia. The incision only needs to be sutured with one stitch using very fine silk thread. Since the long axis of the incision is consistent with the skin lines or expression lines, the postoperative scar is not obvious and the cosmetic effect is better.

Which moles should be removed?

Dr. Li pointed out that in addition to aesthetic factors, in order to avoid turning into malignant melanoma, the following types of moles should be removed:

1. Moles that are susceptible to long-term friction irritation, such as moles located where you wear a bra and on your waist.

2. Moles that show atypical changes. Moles with atypical appearance may become malignant, such as very dark moles, uneven pigmentation (variegated), uneven or irregular edges, unclear boundaries, left-right asymmetry, and statistically larger than 5 mm in diameter.

3. A single mole changes suddenly and rapidly. If moles all over the body change at the same time due to hormonal changes, there is less cause for concern. However, if a single mole changes suddenly and rapidly, it is worth paying attention to.

4. Moles growing in special parts. If a mole grows on the extremities (hands or feet), it must be carefully observed because moles in these places are more likely to become malignant melanoma than moles in other places.
