Ultra Hair Away and placebo effect

i have been using this product for some 18 months now, combined with warm waxing.
i am 59 year old male and had considerable body hair.
i did a test for 3 months by using ultra hair away on the RHS of my pubic area and not on the LHS. the results were impressive! i estimate a 20% reduction in growth and the hair that did grow back was much finer.
now after 18 months i estimate i have a 75% reduction in growth and the little left is very weak.
side effects; seems to ‘improve’ skin tone. stops skin irritation associated with waxing. (and shaving for that matter). no adverse effects noticed at all.

It surprised me to find your site with so much damming reports!
let me say now that i have no affiliation at all with any of these companies.
BUT; i was intending to promote the product as i have had so much success with it; and as i have quite a high public profile, and get asked a lot about hair removal; thought i could make a few bucks!
Can you explain my success please.
yours faithfully,
j

Your three-month self-test had results that can likely be attributed to confirmation bias and placebo effect:

Anyone who epilates regularly over a long period of time is likely to observe a significant reduction in the amount of hair between epilation, regardless of any preparation used in conjunction. This is an effect of removing hair at a faster rate than its growth cycle.

Three months on one test subject is too short a time to make a scientifically valid observation on something with as many variables as hair growth, and with a growth cycle that lasts much longer than three months.

As an example of how hard it is to assess this sort of thing, even with hundreds of test subjects, it’s interesting to look at the nearly 600 women in the original Vaniqa clinical trial. Perhaps the most striking result was how many women in the control group (who used cream with no active ingredient) were observed to have less hair. Of 201 patients, over one-third who used a placebo were assessed by physicians as either “improved” or “marked improvement.”

This huge number of “false positives” means two things for consumers seeking hair removal:

It’s really hard to tell if a new hair removal product is effective or not, especially based on the personal experiences of just a few people.

It’s really easy for manufacturers to exploit this difficulty and make overblown claims suggesting the products they promote are responsible for changes in hair growth.

That’s why you should rely on large-scale controlled studies to determine if a hair removal product is effective.

It’s not that you are not reliable, it’s that there are a lot of reasons your observations are not scientifically reliable.

I hope this explains this very complex issue, and why your observations may have nothing to do with the topical preparation you used.

Take care,
