Hi, my friend. Are you facing hair loss problems? You have come to the right place, over here we can discuss and enquiry any question about hair loss. DIVO scalp specialist will answer your question and provide more hair fall tips for everyone.

The most effective thing you can do externally is massage your scalp to stimulate your hair follicles and increase blood flow. Also the hair strands you see outside your scalp are dead, hair strands lose their nucleus when it exits the skin, so any externally applied products are simply maintaining already grown hair, not producing new growth. 

The active cells that encourage hair growth are located in your follicles. They are the hair root/hair bulb and that's where you want to focus for hair growth. The hair bulb is connected to the dermal papilla (veins), which supply your follicles/scalp with the nutrients it needs to grow.

Another thing you need to know is your hair has a growth cycle. Hair growth cycles are made up of 3 phases: Anagen, Catagen and Telogen. The anagen stage is the most important if your goal is to grow healthy, long hair.

Now to answer your question on what's the best treatment for growing hair. My answer is Nutrition & Scalp treatment. Just like everything else on your body, your hair requires an adequate amount of nutrition to grow long and healthy.
