@colely, fellow @ro_batista asked about cold caps which @muradangie and colleagues wrote about in this Mayo expert blog post
– Mayo Clinic Q and A: Cold cap therapy can reduce hair loss caused by chemotherapy https://connect.mayoclinic.org/blog/cancer-education-center/newsfeed-post/mayo-clinic-q-and-a-cold-cap-therapy-can-reduce-hair-loss-caused-by-chemotherapy-1/

I wasn't aware of laser caps, but did some cruising on the internet. It sounds like there may be some benifit but that more study is necessary.

"A 2016 review (https://pubmed.ncbi.nlm.nih.gov/26690359/) of 21 studies found that low-level laser therapy is a safe and effective treatment in those with male and female pattern hair loss who did not respond to other treatments. However, the authors also noted that more research is necessary to investigate the effectiveness of this treatment.

A more recent review (https://www.karger.com/Article/FullText/509001) investigated the effect of several laser products available to purchase online on males and females with hair loss. The authors found that these products improved hair growth and density with minimal side effects."

I too will be interested to hear if others have tried this.
