There are several common causes for dry hair and weak strands which includes loss of moisture in your hair due to chemical treatments or lack of nutrition. If you notice any such signs, its highly recommend to get into a habit of hair treatment on regular basis.
Here is what I recommend which has proven results due to its natural ability to restore moisture in hair.
To naturally get back moisture to your hair, use a small amount of aloe vera on your scalp and the entire hair strands. After you shampoo your hair, add aloe vera gel to your favourite conditioner or if you want to go all natural then skip the conditioner and apply pure aloe vera gel to your damp hair, leave it on for few mins and rinse off.
Aloe vera will not only provide extra moisture and condition your hair making it soft and smooth but also help in treating hair loss and thinning hair making it healthy.
