Hi Susan!

Thank you so much for taking the time to share your experience with OS-01 HAIR Dermaroller! We're glad to hear that you found the packaging nice and the instructions clear!

We're so sorry to hear that the dermaroller has been grabbing and pulling your hair - that's definitely not the experience we want for our customers! We completely understand your frustration with this, especially since you're trying to avoid hair loss, and it's totally understandable that you would stop using the tool when it's causing the opposite of what you're hoping to achieve.

Sometimes technique and hair type can affect how the dermaroller works, but we absolutely understand that if it's pulling your hair, it's just not the right fit for your needs. Everyone's hair and scalp are different, and what works well for some people may not work for others.

A few tips that may help reduce tugging during use:

Part the hair before rolling so the device is making contact with the scalp rather than running through strands of hair.

Work in small sections and roll along the parted areas instead of over thicker patches of hair.

Use very light pressure — pressing too firmly can increase the chance of hair getting caught.

Roll slowly and in one direction rather than moving quickly back and forth.

Some customers find it easiest to use on slightly damp hair or after brushing thoroughly to minimize tangles.

We really appreciate you giving OS-01 HAIR Dermaroller a try and for sharing your honest feedback about your experience. Your input helps us understand how our products work for different people and hair types!

Hi Lauren!

Thank you so much for your thoughtful feedback and for taking the time to share your experience with the OS-01 HAIR Dermaroller! We're so glad to hear that it's working for you!

We completely understand your concerns about the cap fit becoming loose after a few weeks and the hair getting caught at the sides of the roller, and we really appreciate you sharing this honest feedback.

For the cap fit, we recommend gently pressing the roller fully into the cap and rotating it slightly to help reseat it securely. If hair is catching at the sides, using the dermaroller on clean, dry hair and parting the hair into small sections before rolling can help reduce pulling and improve glide!

Your feedback about the housing design and these practical usage concerns is really valuable to us as we continue to develop products that work best for our customers' daily routines. We want to ensure that the tool remains effective and user-friendly over time.

Thank you for giving the OS-01 HAIR Dermaroller a try and for sharing your experience!
