I purchased the Cappillius Pro laser… I purchased the Cappillius Pro laser cap. I used it for three weeks and noticed I had a splitting headache every time I used it, which lingered all day (and I normally never get headaches). They state on the website that there are no side effects, but I beg to differ. I even discovered that the FDA received a complaint about the same thing as early as 2016. Although I am within the 30 day window to return it, Cappillius is making it difficult to do just that. BEWARE.

Totally worth every penny So my husband and I purchased this based on my sister’s recommendation.... we read all the things and didn’t expect results for a while.... Holy Macaroni this hat is amazing it’s only been almost two months and we are already seeing a difference!! Can’t wait to look at photos a year from now!

Decent results but overpriced and warranty sucks I just had to pay $80 to have a replacement battery and charger shipped after only 18 months of using this laser cap. For $3,000 I expected better longevity and customer service on it. Heck for that price they should throw in a lifetime warranty on all parts. I've bought cars for less than this cap. So, I'm disappointed to say the least and would consider other much less expensive competitors. Having said all that, I did notice some regrowth of hair around my temples after 3-6 months of daily use and a general thickening. So it gets a mixed review from me.

Update on my review … I have written a review about Cappillus already I think it’s below this one. I was looking back at a few reviews and Cappillus haven’t answered any reviews on Trustpilot since 2020!!!! They still haven’t contacted me about my hat……Shambles of a company!!!!!! I REPEAT AGAIN BUYER BEWARE!

Product non functioning after 12 months and Non existing Customer Service I bought capillus in March 2022 in Hong Kong … after 12 months the battery stopped working already… I tried to ask for a call for customer service… but then it’s only in US time zone and they don’t call outside US… therefore we sent an email… and we attached the videos… then they mentioned that was the battery… so they suggest to buy a new one… we bought the battery… around 300 USD… including a huge shipping cost…. Then… they cancelled the order… then we should have received the refund… but not yet… Honestly for a product which costs as much (ca. 2,000 USD) you would expect a decent level of customer service… Instead nothing… so given the costs for sure better to use any other alternative.
