This company has absolutely horrific communication. Their phone might as well be non-existent and their emails are incredibly slow to answer. I've been waiting for one month for an almost $2,000 product.
Once I finally got an email response they are generic in nature with no resolution.

Excellent results from this cap since 2019!

I have been using this cap since early 2019. During menopause, I noticed hair loss and after reading the science behind it, I decided to give it a chance. Over the years, I couldn't be more satisfied with the results. I'm a consistent user and the cap has proven to be durable for years! The outcomes have truly exceeded my expectations.

Continued success since 2019

Since early 2019, I have been using this cap during menopause as I dealt with hair loss. The scientific backing convinced me to try it, and I couldn't be more satisfied with the results over these years. I use it regularly, and the cap is durable, lasting for years!

Notable results in just a week

Ordering the cap was straightforward, and it arrived promptly. In just over a week, I've noticed fine baby hairs sprouting where there was none for some time. I'm optimistic about the results in the coming months.

A hopeful journey against hair loss

Having battled female pattern baldness for years, I nearly lost hope. However, investing in this laser cap, combined with topical treatment, has led to real regrowth for the first time. It's not an instant fix, but consistency is key, and this method has truly boosted my confidence. Highly recommend giving it a shot!

Decent product, but read the fine print!

My order faced delays, but customer service was quick to respond and keep me informed. The cap works well, though it's more generic than I anticipated, and the design isn't discreet. I'm cautious about wearing it outside. It's tricky to verify it's on, and if the battery dies mid-use, there's no alert. I've only had it for a few weeks, so I'm still assessing its value. I wish I had paid more attention to the warranty details, as it's a significant investment.

Affordable and time-efficient

The process is simple: just 6 minutes daily at a set time. I opted for the dualwave model tailored for moderate budgets. The pricier option was too costly, and the cheaper one required 30 minutes, which I couldn't manage. This model is quick and easy. I appreciated the email reminder to establish a routine before the cap arrived. The treatment is painless, and I feel warmth on my scalp towards the end. Consider trying this model!
