Hair Growth in Children

Many factors determine hair growth in children. Diet, hormones and genetics affect their hair growth process, making it slower or quicker. Growth spurts also affect hair growth in children.

Time Frame

After being six months in the uterus, thin hairs cover the baby´s body, this hair is called Lanugo. During those six months, glands secreting oils and hair follicles have been formed. At this point, around 100,000 follicles have been formed on the scalp, but many of these hair follicles will stop growing hair over time.

Growth Spurts

Babies are born with different hair growth; some of them born bald while some others have a full head of hair. But this is not exactly a sign of what the child´s hair growth is going to be in the future—he/she could actually have hair growing faster or slower later on.

During the first year of their lives, children experience a dramatic growth spurt, after that phase they show steady growing levels until they reach adolescence.

A second growth spurt comes with puberty. A child´s hair growth is affected by these growth spurts, and especially by the one experienced during puberty, because this is the time when new hair starts growing in more areas of the body.

Hair Loss

Children can suffer from hair loss problems also. Many factors can cause these problems, including common infections, hormonal changes, some bodily disorders and ringworm. Ringworm promotes hair breakage, irritating the hair shaft. A doctor can prescribe medication to eliminate ringworm. Allergic reactions, some hair products and dry hair could lead to an itchy scalp, when children scratch their heads more hair tends to fall off their heads.

Hair Growth Cycle

Hair grows following a cycle; it starts with the Anagen phase. In this period hair follicles are active and there is production of new hair. While in this phase, hair strands on scalp will keep growing for two to six years on average. Hair growth rate is usually one to two centimeters per month during the Anagen period. Once Anagen stage comes to an end, the Catagen stage starts. In this phase, hair shaft narrows and hair follicles experience slow changes for two to three weeks. After the Catagen phase comes the Telogen phase, where follicles stay inactive, or in the state of rest, for about 100 days. The cycle completes with the Exogen phase. At this stage hair strands will shed and the Anagen will start growing new hair.
