So depressed by this I paid to see a tricologist and did some research on my own
First make sure the hair you have is kept healthy, you need strong hair for extensions etc.
Eat protein for breakfast
Take iron, vit c, b12 and folic acid
If like me it is thinning at the front, change your parting
Cover really thin bits with Toppix hair powder
Minoxodil is the only drug licensed to work but it must be used everyday
Cut out shampoos with sulphates, use organic
Massage your scalp to get blood to the follicles and use overnight treatments. I like coconut oil and I wear a nylon cap overnight to protect my pillow.
Ketonozole shampoo for dandruff has been used off label to slow down thinning. Condition well afterwards.
Also you might try Canesthan mixed with your shampoo, side effect hair growth.
If all else fails Hot Hair, Qvc etc have braided hair bands, clip in fringes.
Do not do what I did and howl in the bath!!!
Love you all.
