Severe Hair Fall, Management of 'Low' Blood Pressure related Dizziness, Chin Acne - #27246

Dear Doctors, Thank you very much for taking time out to help people with their ailments. We truly appreciate it. I am a 45 years old female. I have listed below common questions that doctors ask/advice about and problems. Would greatly appreciate assistance regarding the same. Hormones/Surgery: My Uterus, Fallopian tubes and Right ovary were removed a few years ago (My left ovary is intact) Diet: I am a Vegetarian. I eat a reasonably good diet of vegetables, fruits, pulses, grains & dairy. I generally avoid white sugar and take healthier forms such as Jaggery, Panagarkandu or honey. I drink 2.5 cups of coffee & tea a day. I feel very dull and tired if I do not take it. I catch a headache too. I discontinued it for 3 years, but found no improvement in my overall health, so, added it back into my diet. Hair Oils: Both Coconut oil & Sesame Oil cause my body to cool down a lot and I therefore get severe migraines often on hair wash days along with experiencing a lot of tiredness. I catch cold too in winters when I use these oils. Hair wash: I use Meera Shikakai powder to wash my hair after oiling once a week (I wash after 20-30 minutes). Vitamin C intake: My body cools down and I catch migraines and cold if I take citrus (Vitamin C) fruits in the forms of fruits as such or juice such as Lemon juice, Kiwis, Amla juice, orange juice, etc. But, I instead try to include some of them in other ways such as pickles or lemon rice, etc. This does not affect me. Problems: 1) I have been suffering from severe hair fall for a few years now and my hair volume has reduced drastically. I have tried AVP Durdurakera tailam (coconut oil base) for a year as recommended by an ayurveda doctor and then followed with AVP Chemparathuyadi tailam (coconut oil base) for another year. No improvement and infact, hair fall is worse now. I have been using betel leaves and small onions infused in coconut oil for 2-3weeks now, but that is also causing a lot of hair to fall. 2) I also get acne and white heads on my chin now and then and the chin feels bumpy always. It is slightly better with using 'clean and clear' face wash once a day. 3) My blood pressure falls down often and I become very dizzy. I use salt and/or jaggery to feel normal again along with resting. My pressure also falls post having meals after ekadashi fasting (I take coffee/tea/milk alone during fasting days). Kindly suggest easily doable and practical remedies for the above problems as too many complicated medications just makes it difficult to comprehend/follow. Thank You very much once again for your time. Regards
