According to estimates from the American Society of Plastic Surgeons, around one million laser hair removal procedures were carried out globally in 2018. The growing demand for fast, affordable, and effective hair removal solutions has made at-home laser devices increasingly popular. These devices use Intense Pulsed Light (IPL) technology and are often compared to professional salon treatments for their ability to slow down hair regrowth over time.
The results of at-home laser hair removal vary based on several factors, as is the case with any cosmetic treatment. This guide explores the research, data, and evidence on how long it takes for home laser devices to deliver visible results.

Part 1: PCOS – How Long Does It Take for At-Home Laser Hair Removal to Work?
Hirsutism refers to excessive hair growth in women in areas where it is typically minimal or absent. It is primarily caused by elevated androgen levels in the bloodstream. Women with PCOS often find that managing hair regrowth is challenging, as hormonal imbalances can make the process slower.
While at-home laser hair removal can significantly reduce hair density, it typically takes longer for those with PCOS to see results. Most users notice a difference after 8–12 sessions over a period of 2–4 months. However, consistent maintenance is essential to control regrowth. For optimal results, laser treatment should be combined with medical management targeting the underlying hormonal imbalance, as PCOS disrupts the hair growth cycle. Patience is key, as individuals with PCOS may require more time to achieve long-term hair reduction compared to those without the condition.
Part 2: Thyroid Imbalance: How Long Does It Take for At-Home Laser Hair Removal to Work?
Both hyperthyroidism and hypothyroidism can disrupt the hair growth cycle, leading to uneven or slower results from at-home laser hair removal. Typically, users require 6–10 sessions over 2–3 months to see visible improvements. However, hormonal fluctuations can delay progress and impact hair reduction effectiveness.
Hair growth related to thyroid imbalances may take longer to respond to laser treatment and can be more resistant to change. To achieve the best results, stabilising hormone levels through medical intervention is crucial. Individuals with thyroid conditions should maintain regular use of their devices and be prepared for a gradual improvement rather than immediate results.
Part 3: Pregnancy: How Long Does It Take for At-Home Laser Hair Removal to Work?
Pregnant women should avoid using at-home laser hair removal devices due to the hormonal changes that affect hair growth, as well as the lack of substantial safety data regarding their use during pregnancy. Temporary hormonal shifts can trigger increased hair growth, making laser treatments less effective.
For these reasons, it is recommended to postpone treatment until after childbirth, when hormonal levels stabilise. This ensures both safety and optimal results. Post-pregnancy hair growth patterns typically regulate over time, making the treatment more effective.
To achieve the best outcome, six to eight sessions spaced over two to three months are generally advised after giving birth. It is also crucial to follow device instructions carefully, particularly as postpartum skin may be more sensitive. Conducting a patch test before full treatment can help prevent irritation or adverse reactions.
Part 4: How Long Does It Take for At-Home Laser Hair Removal to Work on Sensitive Skin?
At-home laser hair removal devices are generally suitable for people with sensitive skin, but extra precautions should be taken to minimise irritation, burns, or discomfort. On average, it takes 6–8 sessions over 2–3 months to see noticeable results, similar to those with normal skin. While hair regrowth occurs, it is significantly reduced over time.
For those with sensitive skin, using devices equipped with skin tone sensors or cooling technology, such as the Ulike Air 3, can enhance comfort and safety. Performing a patch test before full use is essential to assess skin reactions and avoid irritation. Proper aftercare is equally important to maintain smooth, irritation-free skin. Those prone to sensitivity may also benefit from consulting a specialist for personalised guidance.
Part 5: Factors Influencing At-Home Laser Hair Removal Efficiency
Several key factors affect the efficiency and speed of at-home laser hair removal treatments.
Hair and Skin Tone
Home laser hair removal devices target the melanin in hair follicles. These treatments are most effective on dark hair against light to medium skin tones. Research published in the International Journal of Dermatology found that individuals with fair skin and coarse, dark hair saw an 80% reduction in hair density after 12 weeks of consistent treatment.
However, results may be less effective on darker skin tones or light, blonde, or grey hair, as the laser or IPL technology may struggle to differentiate between hair and skin pigments.
Treatment Consistency
Consistency is crucial for achieving optimal results. Most at-home devices recommend treatments every 1–2 weeks for the first 8–12 weeks. Studies show that missing sessions or using the device less frequently can lead to slower hair reduction and reduced effectiveness.
Pain Tolerance
Some devices offer adjustable intensity settings, which can impact both comfort and effectiveness. While higher energy levels may cause more discomfort, a 2019 Consumer Reports study found that higher-intensity treatments generally delivered better results. Choosing a device with customisable settings allows users to balance effectiveness with comfort.
Part 6: Tips for At-Home Laser Hair Removal Success
The most fundamental step is to follow the treatment guide, ensuring it aligns with your skin type and condition. For optimal results, the treatment area should be shaved before each session, as hair on the surface can interfere with the laser's ability to target the follicles effectively. Using the correct machine settings, following the recommended treatment intervals (every 1–2 weeks), and maintaining proper aftercare—such as avoiding sun exposure and keeping the skin moisturised—will significantly improve results. Individuals with underlying hormonal imbalances should consult a healthcare professional to optimise their treatment approach.
Conclusion
At-home laser hair removal requires time and consistency to deliver noticeable results. Studies suggest that visible hair reduction typically occurs after 12 weeks of continuous use. Effectiveness depends on factors such as hair and skin type, device technology, and adherence to the recommended treatment schedule.
Devices like the Ulike Air 10 and Ulike Air 3 have been reported to reduce hair by up to 80% after a full treatment cycle. However, strictly following the manufacturer's guidelines is essential to maximise results and minimise the risk of side effects.
