The mystery of babies whose hair won't grow

You've no doubt noticed it yourself or seen it among friends and family — some children seem to struggle to grow their hair. This is often a source of worry for parents. Why is their child's scalp not showing a lovely thick head of hair, even after several months? Let's explore together the different reasons that might explain this intriguing phenomenon.

Different hair types and how they grow

The existence of several hair types can explain the major variations we observe in terms of hair density. Not all humans have the same number of hair follicles on their scalp — this quantity is determined by genetics. There are generally three hair types:

Fine hair: this hair type is characterised by a small hair diameter, which gives the impression of fewer hairs.

Thick hair: conversely, thick hair has a larger diameter, giving the impression of greater hair density.

Curly hair: curly hair has a spiral shape and is particularly resilient, with variable hair density.

To determine your baby's hair type, it is important to take into account both the number and distribution of hair follicles, as well as their individual characteristics.

Natural factors influencing hair growth in babies

Heredity

As mentioned above, genes play a fundamental role in the appearance of the scalp. A baby who has inherited low hair density or fine hair will naturally find it harder to see their hair grow quickly.

The rate of hair growth

Not all hair grows at the same speed: on average, adult hair grows between 1 cm and 1.5 cm per month. In babies, the growth rate is generally slower, especially during the first few months of life. What's more, hair follows a cycle (anagen, catagen, and telogen) that it adheres to faithfully. It is therefore quite common for some babies to go through a "resting" phase before enjoying a welcome burst of growth.

Possible causes of hair not growing in babies

Alopecias

In some cases, a lack of hair growth may be due to medical conditions such as specific forms of alopecia that primarily affect children. For example, alopecia areata, which is characterised by patches devoid of hair, or alopecia universalis, which results in a complete absence of body hair.

Stress

It may come as a surprise, but children can experience episodes of stress too! During these moments of intense anxiety, the body secretes cortisol. This hormone is often responsible for hair loss in adults and could also have an impact on young children. It is therefore worth ensuring that your baby grows up in a calm and peaceful environment, conducive to the healthy development of their hair follicles.

Diet

A balanced diet is essential for children's healthy overall development, including that of their scalp. Proteins, vitamins, and minerals are indeed indispensable for the health of stem cells and hair bulbs. Make sure to provide your child with all the nutrients they need to encourage the growth of those precious locks.

Sleeping without restriction: the importance of your baby's sleep position

Side preference

You may have noticed that your baby seems to have thinner or less developed hair on one side. This is mainly due to sleep position. Babies generally have a preferred side on which to sleep, meaning their scalp rests constantly on the same area. It is therefore important to regularly vary your baby's sleep position to avoid excessive friction that could cause premature hair loss.

Taking a measured view of the situation

Finally, some situations can create the illusion that a baby's hair is not growing when in fact it is. Some children simply have very fine blonde or curly hair that only takes on its true appearance over the years. It is also possible that you are falling into the trap of comparison, particularly when comparing your child with their peers.

Whether your baby proudly sports an abundant downy fluff or just a few sparse strands, remember that every little head is unique and that, more often than not, nature eventually takes its course in its own time. So — patience, and trust in those little charming heads that enchant us day after day!
