I've been using Revivogen Bio-Cleansing shampoo for twenty-two years.  I have also used their hair growth serum periodically for those times when I have had health challenges.  As with any hair growth product, it can't prevent all hair loss during times when your health is challenged, but once you are on a well path, I've seen this product boost hair growth every time and maintain it beautifully.

I really recommend this hair product for hair loss or maintaining what you have.

Thanks for sharing! They sure are proud of it - a bit too expensive for me right now but will definitely try it when my budget growse. :) 

You're welcome. 🌹

There are some other options that work just as well, that I've used.  I really like the P'urador hair product line, and specifically for growing hair is their Apple Cider Vinegar shampoo and conditioner. The ingredients are very similar to Reviogen and may be even better.  The only con is that it smells like vinegar and tea tree oil, other then that, it works and detangles beautifully.

Another very simple solution that is a healthy option, is simply adding castor oil to your shampoo.  On my second pass of cleansing, I'll use a dime size amount of castor oil, and mix it in with my shampoo.  Castor oil is excellent for hair growth and maintaining nice hair.  I tried putting the castor oil in with my conditioner and it was a fail, so I mix it in with the shampoo instead.  You can also use it on your eyebrows if needed to stimulate some growth.
