Re: herbal oils for hair..
I have never used any of the brands you mentioned. But FF, if you are concerned, you may want to mention this to your doctor. It may be due to some nutritional deficiency, stress, some medication, etc. A little hair loss is normal but all of a sudden substantial loss of hair can be a matter of concern.
However, if there is no underlying medical issue, then it may be worth a try. I have used olive oil, almond oil, even amla oil and they are very good for nourishment of the hair and scalp.
