Grooming precautions
Can I use Nair directly on my genitals?
No. Nair states that its bikini-area products are for use nearby, not directly on the genitals. Do not use a general body cream or spray on the scrotum. Check the exact package for permitted areas, patch testing and timing. Nair's general guidance gives a maximum of 10 minutes, with shorter limits for some products. Never leave it on for hours or exceed the label's limit. Read Nair's official directions and warnings.
What shaving advice should I follow?
The American Academy of Dermatology's general shaving guidance recommends moistening the skin and hair, using shaving cream or gel, shaving in the direction of hair growth and rinsing the razor after each stroke. It does not establish that a safety razor is the safest choice for scrotal skin. For an intimate trimmer, use only the areas, guards and technique specified by its manufacturer. Ask a dermatologist if you are unsure about your skin or have irritation. Read the AAD's general shaving guidance.
Does shaving make hair grow back thicker?
No. Shaving does not change hair thickness, color or growth rate. The cut tip can feel coarser as it grows out. Read Mayo Clinic's explanation.
