iGrow vs. Theradome Pro Lh80 – Comparative analysis

iGrow vs. Theradome Pro Lh80 – Comparative analysis: Every day, most people lose about 100 strands of hair from their scalp. While the majority of people grow those hairs grow back, some people don’t due to age, heredity, hormonal changes, medical conditions, such as lupus and diabetes, poor nutrition, side effects of medical treatment, such as chemotherapy, and of course stress.

And most common treatments to stop hair loss and possibly reverse it include: medications such as minoxidil (Rogaine) and finasteride (Propecia), hair transplant surgery and laser therapy

The theory of laser treatment for hair loss is that the low-dose laser treatments invigorate circulation and stimulation that encourages hair follicles to grow hair.

And studies have yielded encouraging results:

According to a 2014 study, low-level laser therapy appeared to be safe and effective for hair growth in both men and women.

2013 study of 41 males ages 18 to 48 found that laser hair treatment provided a 39 percent increase in hair growth over a period of 16 weeks.

There are a number of reasons that advocates cite to encourage participation in the procedure, including:

  • it’s non-invasive
  • it’s painless
  • there are no side effects
  • it increases hair strength

Let’s compare these two models but first, there is still a better product out there.
