Some of her suggestions sound easy enough, so why not give a try.
Also, rotate substances. The body habituates so that a remedy that was working may stop working. If you give your body a break from it, it will often start working again. Energy testing shows you when you need to rotate.
A Native American woman told my aunt to take the mineral COPPER. She did, and her hair came back from gray. Make sure you energy test this, because you can overdose on copper. Plus we can't let ourselves be fooled into thinking that what worked for one person will work for another.
In addition to copper, iodine, and pantothenic acid, I've seen benefit from B-12, chlorophyll, and DMAE, as well as coconut oil put directly on the hair.

Your body is always losing and replacing its hair. A normal hair cycle should lead to more hair. Growth cycles are related to energy balances, so when the energy between head and hair has gone awry, hair graying and hair loss is often a result.
Factors that interfere with the cycle – like medication, illness, infection, or chemicals – have the potential to stop hair from being formed properly. It can get dry, it can go gray, and it can fall out.
Balancing the energies in the head can counter this (use Neurovasculars, Crown Pull, Rooster Comb Hold, meridians, etc.)
Also you can balance the energies by practicing:

Problems with the thyroid or pituitary glands can also cause graying and baldness, so test and balance the associated meridians. A very simple technique is to tape a magnet or two onto your hairbrush so the south side faces your scalp. The energy of a magnet's south side stimulates growth. Many people have shown me positive results after I suggested they do this.
Not only was color restored to graying hair when using the magnet, but their hair grew in thicker. When this approach works, it is usually because there is a sebaceous gland problem. In fact, simply massaging the sebaceous glands on the scalp can also help with hair issues.
To close, one special story. The pitch black hair of my wonderful old friend, Jimmy Wong, went pure white after a heart attack. He used a Chinese herb, He Shou Wu, and it returned to black.
