Remember it ISNT always from DHT-- ppl always blame that.
I'm not a medical genius but let me give you some cues
You see you have to think Logically.
-Spiro is a diruetic(typo), it takes out all of your water in the system, adjusts blood pressure, AND makes skin dry!
-So it could possibly be from not drinking enough water, dry scalp and blood circulation to the scalp.
Now HRT can cause some stress and depression.- this can cause chemical imbalances- this can cause hair loss(temporary loss)
To fight depression and stress take vitamin B-6 and B-12. Vitamin C is depleted by estro which needed for hair growth and estro's metobalization. Take protien(not too much).
do cardio work for 45 minutes 4 days a week- it will bring oyxgen to the scalp, circulate estro better- thus estro can go to the scalp area. So if the AA's and hormones circulate more it's logical to say that testo would drop and so would DHT.
Avoid shampooing your hair more then 4 days in a week- as this dries the scalp.
Go in a Indian Supermarket(trust me) and buy Coconut Hair Oil, Almond Hair Oil, Henna Hair Oil.- i bought a Indian Hair oil that has Henna, Coconut Oil, Some herbs and Fenugreek which is good for male pattern baldness.
Now take these oils and massage your scalp for like 10-15 minutes with it- don't just put it on your hair, massage your hair roots and scalp with the oil- put lots of it!- Now these oils are greasy so put it on night with a towel on the pillow. Wake up in the morning and if it's the day to shampoo then shampoo it. If it's not the day to shampoo then just rinse your hair with water very well.
I reccommend you put this oils in small amount on your hair for dryness during the day and I recommend to massage this on your scalp at night.
Avoid curling irons, blow drying, Hair gels, hair sprays and coloring your hair.- these have chemicals and the heat from curling irons as well as blow drying dries the scalp.
You should not smoke, drink, drugs etc-common sense!
Try to get 8 hrs of sleep or more!
You could try Rogaine(I heard you have to keep taking it though)- perhaps Propercia.
So again- all the stuff I listed here is common sense!- It's knowlegde that you have which you need to apply.
Good luck and I hope you have gorgeous hair- its terrible for a women to go bald.
