It is quite confusing to determine whether hair grows from root or tip. But there are certain evidences which might clear your confusion. Haircut and hair color are the proofs that hair grows from the root. This is the reason why your natural hair appears after some time of hair color or permanent straightening.
Any hair that you can actually touch and see is nothing but dead cells. Root is the only living part of the hair. Undoubtedly, hair grows from roots and not the tips.

Hair growth or loss in human beings is neither seasonal nor cyclic in nature.
There are three basic stages of hair growth: Catagen, Telogen and Anagen.
This transitional phase lasts for about 2-3 weeks only. During this phase, growth retards and the outer root sheath attaches to the root of the hair. Catagen marks the onset of the formation of club hair.
Telogen is the resting phase which lasts for nearly 100 days for the scalp hair. This phase is comparatively longer for hair on eyebrows, eyelashes, arms and legs.
Anagen is an active phase of the hair during which the cells in the root of the hair grow quickly. New hair is formed and club hair is removed during this phase of the hair growth cycle. During this phase, hair grows about 1 cm every 28 days. Scalp hair remains in Anagen phase for 2-6 years.
On the other hand, people with long hair have a very long active phase of growth.
This is the reason why hair on other body parts is shorter than scalp hair.
Hair trimming removes the dead ends and leaves the healthy hair behind making it to grow faster than before.
