What do you recommend to counter male pattern baldness?
If the hair follicles are dead already they are not going to come back. If the hair follicles are still alive you will see little hairs in the follicle. In this case the best thing is licorice root, which is a fantastic DHT blocker. You can use it both internally and externally. For external use you can make a tea from the licorice root by boiling it for 15-20 minutes in a covered pot. You can also add a little yucca root if you want, which helps to stimulate hair growth topically. Then let it sit and steep until cooled. Strain the tea and put in a glass bottle. Add a spoon full of rubbing alcohol or a high proof alcohol per 16 ounces as a preservative. After showering and towel drying the hair use a quarter teaspoon of the tea to massage in to the scalp as a DHT blocker.
I have heard that sesame oil is also a good DHT blocker, but licorice root will not leave the hair oily.
Other things that will help is massaging the scalp frequently. This increases circulation to the scalp like the drug Rogaine (minoxidil) does but without the side effects of the drug. And use a boar bristle brush, which helps to massage the scalp and does not damage the hair like nylon brushes can.
