In 1928, medical research confirmed that shaving does not alter hair growth speed or thickness. Whether shaving, trimming, or removing leg hair, none of these methods cause hair to grow thicker or faster.
The perception that hair appears thicker after shaving may stem from the visually larger cross-section of the hair shaft at the cut surface.
Misconception 2: Plucking is better for hair removal
Plucking is neither more effective nor preferable—it's time-consuming, labor-intensive, and potentially damaging to the skin. The act of plucking itself causes significant irritation, and excessive force may pull on the skin, causing unnecessary injury.
Plucking can lead to skin laxity, hyperpigmentation, and other issues. Improper technique may even result in uneven skin texture, creating an unsightly appearance.
Misconception 3: Hair removal affects sweat secretion
Human hair follicles and sweat glands are two separate structures. Shaving shortens hair, while laser hair removal destroys the growth cells within the follicle. Neither damages sweat glands, so neither affects perspiration.
Misconception 4: One hair removal session is sufficient
A single session is far from enough. Typically, 3 to 5 sessions are required to achieve stable hair reduction. The purpose of hair removal procedures is to destroy hair follicles, leading to two possible outcomes:
First, the follicle is completely destroyed and ceases hair growth. Second, the follicle is not fully destroyed and requires multiple sessions to eliminate it permanently.
Another reason is that hair removal targets only hair in the growth phase, while hair in the resting phase remains untouched. Once resting-phase hair grows back, it requires further treatment. Therefore, 3 to 5 sessions are generally needed to achieve relatively stable hair reduction.
How to Alleviate Post-Hair Removal Issues
1. Small Red Spots After Hair Removal
Failure to exfoliate before treatment may cause numerous red spots post-procedure. Regardless of the hair removal method chosen, exfoliation must be performed 24 hours prior to thoroughly remove dead skin cells. This prevents newly emerging hairs from becoming trapped beneath the skin, which can lead to red spots.
2. Residual dark dots after hair removal
Some individuals shave immediately after morning showers, but this yields poor results. During sleep, legs experience swelling that conceals some hair follicles. Upon waking, these hairs may not have fully emerged, leading to residual dark dots after shaving. Schedule hair removal in the evening for more thorough results.
3. New hair growth appears thicker and darker
Frequent hair removal can cause new hair to grow back thicker, darker, and coarser. For waxing, schedule sessions every 3-4 weeks to allow new hair sufficient length for effective removal. Leg and bikini area hair typically requires about 6mm of growth before optimal waxing results.
4. Significant discomfort after hair removal
Hair removal during menstruation may cause noticeable pain. Hormonal changes around menstruation increase blood flow and heighten sensitivity to external stimuli, making waxing or depilatory creams more painful. Schedule hair removal during the ovulation phase instead.
5. Skin abrasions from shaving
Repeated razor blade use without lubricant can cause skin nicks. Lubricant not only reduces blade irritation but also lifts extra hair for smoother removal. Apply an adequate amount to the treatment area to help hair stand upright, ensuring a cleaner shave.
6. Enlarged and Dry Pores
Failing to apply moisturizer promptly after shaving can lead to enlarged pores and dryness. After hair removal, rehydrate the skin immediately: first rinse with lukewarm water, then apply a tightening toner, and finally finish with a small amount of moisturizer.
