Final answer:
To prevent ingrown toenails, clip nails straight across and not too short. Nails are made of keratin and grow from nail beds. Certified nail technicians can help reduce the risk of nail and skin infections.
Step-by-step explanation:
To avoid ingrown toenails (onychocryptosis), it is advisable not to file or clip the nails too short or in a rounded fashion at the edges. The free margin of the nail, which is the part that extends beyond the distal end of the finger or toe, should be trimmed straight across to prevent the sides of the nail from growing into the surrounding skin. Nails are composed of keratin-filled epidermal cells and lack nerve endings, which is why cutting them does not cause pain. However, improper trimming can lead to painful conditions such as ingrown toenails.
Professional nail care, such as manicures and pedicures, carries health risks of skin and nail infections like dermatophytic skin infections (athlete's foot, ringworm, jock itch). It's important to ensure that professional nail technicians have adequate training and certification to mitigate these risks. Fingernails and toenails serve several functions, including protecting our digits and enhancing tactile sensation.
