Frequently Asked Questions
FAQ
How does Cyperus Rotundus Oil help slow hair regrowth?
Cyperus Rotundus Oil contains naturally occurring compounds, including flavonoids, that have been studied for their potential anti-androgenic activity. Androgens are hormones that stimulate hair growth in certain areas of the body. By helping reduce the activity of these hormones at the follicle level, the oil may slow the hair growth cycle over time, resulting in regrowth that appears finer, lighter, and less noticeable with consistent use.
Is this product safe for sensitive skin?
Our formula is made with plant-based ingredients and does not contain harsh chemicals, parabens, sulfates, or artificial fragrances. Most users tolerate it well, including those with sensitive skin. That said, we always recommend performing a patch test before first use. Apply a small amount to a discreet area and wait 24 hours. If irritation occurs, discontinue use and consult a dermatologist.
Do I need to shave, wax, or remove hair before applying the oil?
The oil can be applied directly to areas with existing hair, including fine facial hair or peach fuzz. However, research and user experience suggest that applying Cyperus Rotundus Oil after hair removal methods such as shaving, waxing, or sugaring may improve results. Hair removal allows the oil to better reach the follicle, where it can be most effective.
Are the results permanent?
Cyperus Rotundus Oil does not permanently destroy hair follicles. Instead, it works by helping slow the biological processes that drive hair growth. While some users notice visible changes within a few weeks, long-term improvement typically requires consistent use over several months. Continued application is recommended to maintain results and prevent regrowth from returning to its original pattern.
What ingredients are used in this formula?
The key active ingredient is Cyperus Rotundus (Nutgrass) extract, a botanical traditionally used and studied for its hair-thinning and regrowth-slowing properties. The formula is designed to be gentle and is free from parabens, sulfates, artificial fragrances, and other harsh additives, making it suitable for most skin types.
Can I use this oil with other skincare products?
Yes. Cyperus Rotundus Oil can easily be added to your existing skincare routine. Apply a few drops to clean, dry skin and allow it to fully absorb for 5–10 minutes before applying lotions, serums, or moisturizers. For targeted areas such as the face, we recommend precise application (for example, using a cotton swab) to avoid affecting areas like the eyebrows where hair reduction is not desired.
Are there any known side effects?
Most users do not experience side effects when using the oil as directed. However, as with any topical product, individual responses may vary. Mild redness or irritation has been reported in rare cases, particularly when combined with other hair removal treatments. If irritation occurs, stop use and consult a healthcare professional.
When should I expect to see results?
Results vary depending on hair type, skin type, and consistency of use. Some users report noticeable changes within a few weeks, while others may require 8–12 weeks of daily or routine application to see visible improvement. For best results, we recommend consistent use as part of a long-term hair-reduction routine.
Can this oil be used on all areas of the body?
Cyperus Rotundus Oil is suitable for many areas of the body, including the legs, arms, underarms, and face. Avoid contact with the eyes and mucous membranes, and use caution on highly sensitive areas. Always perform a patch test before applying to new areas.
Is there scientific research supporting Cyperus Rotundus Oil?
Several studies have explored the effects of Cyperus Rotundus extract on hair growth. Research published in peer-reviewed journals, including Aesthetic Surgery Journal, suggests that the oil may help reduce hair density and thickness over time and may be as effective as certain laser treatments for decreasing hair growth. While results are promising, ongoing research continues to further evaluate its long-term efficacy.
