The research behind Keen3

Keen3 Pro was developed through NIH-funded research. Our pilot study found that pairing an awareness-building vibration with therapy-backed strategy suggestions was associated with significant reductions in hair-pulling severity and impairment. AND 100% of participants said they'd recommend it. Read the study.

*Keen3 is recommended for hair pulling and skin picking behaviors on the face, scalp, shoulders, and nail biting. For finger picking or gestures below the shoulders, please email us. Even if Keen3 is not right for your gestures, you can still break the cycle with behavior change e-course, 1:1 peer coaching, group meetings and online community.

Meet the inspiration behind Keen

Hi! I'm co-founder Aneela Idnani. I needed something to help me build awareness of my trichotillomania. I've learned, both personally and through serving the community for 9+ years, that the vibration is just the first step. We needed Keen3 to be able to deliver relevant strategies to users so they'd know what to do when they felt a vibration!

Keen3 FAQ

When will Keen3 be shipped?

We estimate January 2027. 

How is Keen3 different from Keen2?

There are three main upgrades:

Keen3 has a high quality AMOLED touchscreen, like you see on most modern smartwatches.

Keen3 Pro delivers behavioral and coping strategies tailored to your needs, straight to your phone/band, when you need them. 

Keen3 gives you light daily suggestions to keep you consistent in BFRB management.  

Keen3 has swappable strap colors, offering extra customization.

How is Keen3 research-backed?

When creating Keen3, we referenced the research we've done so far with both NIH and NSF, as well as our ongoing study with NIH. In the pilot trial of our ongoing study, the HabitAware Methodology was associated with significant reductions in hair-pulling severity and impairment. AND 100% of participants said they'd recommend it. 

The approach is grounded in existing evidence-based cognitive-behavioral approaches to managing BFRBs.

What is Keen3 Pro?

Keen3 Pro refers to features only accessible through a Keen3 Pro subscription.

You receive a year of free access when you purchase Keen3. Your year starts when you sync the band to the app. There is no bonus year for syncing two Keen3s at the same time.

You will receive several emails a week before your subscription renews, giving you time to decide if you'd like to continue!

Keen3's straps are silicone. Keen3's body is stainless-steel and nickel free.

Keen3's straps are one size fits all. 

What are the size options?
