By about two years of age, your child's vellus scalp hair will be replaced with thicker, longer, and darker hair. These hairs are your child's terminal hairs—adult hair.
Your baby's hair texture will change until they reach the age of two. The soft hair texture of baby's locks often changes into more wavy or straight strands around the age of two. Your baby will have three changes in their hair texture during the first 24 months.
Your baby's permanent hair will likely begin to appear around the six-month mark. However, your little one may grow their childhood hair as early as three months or as late as 18 months. Every child is different. It's considered healthy and normal for babies to grow their big-kid hair any time before two years of age.
A child with completely straight hair after air drying obviously has straight hair. If there is a slight wave to it, but it doesn't curl up then it is considered wavy. If your child has larger curls, but they are not tightly wound, then your child has curly hair.
Therefore, babies may start off with fine, straight hair, or even thick, lush locks, and after just a few months or a year, their “inherited” curls may begin to pop up! Just like adults, changes in growth cause changes in our baby's skin and hair as well.
Puberty, menopause and pregnancy all cause hormonal shifts that can make your tresses go from straight to curly hair. In fact, 40-50% of women experience major changes in their hair while pregnant or breastfeeding.
It's impossible to say if a toddler's curls will stick around even if you would love to know. Infants go through so many stages with their texture and appearance as they grow. But if you keep your child's hair healthy, and wait patiently, it's possible those curls will stick around. Only time will tell!
It's true, you're not crazy, your hair texture can and does change throughout your life for a variety of reasons. Some people have pin straight hair as children that then curls up once they become teenagers, or others have tightly coiler hair when they are younger that loosens into curls as they get older.
It's not really a question of whether your child will inherit the hair gene from Mom or Dad. Instead, your child inherits a myriad of genetic factors that all add up to their very own locks.
Babies' Hair Changes After Birth
But don't worry, it grows back. Your baby's hair falls out because of hormone changes in their body. When they're growing in your womb, they get large amounts of hormones from you. After birth, these hormone levels plummet, causing their hair growth to stop.
Over time, your hair may become more curly, straight, thin, or coarse. Many of these changes are brought on by the maturation process, but there are also plenty of reasons why this could be happening that have nothing to do with age. Stress, diet, and hormone changes all play a part in your hair's texture.
Baby hairs are: Finer in texture than regular (terminal) hairs. Tend to be lighter in color. Often described as wispy.
Curl pattern is genetically programmed just like eye color, height, and most other aspects of phenotype. Throughout our lives, however, we experience biological changes to our hair texture. By diameter, our hair tends to become gradually thicker into adulthood, thinning again in middle and old age.
Like all type 2 hair, 2c hair is wavy, but that often feels like a technicality. Your S-bend hair is thick and the waves start at the roots. If you've ever been confused about whether your hair is wavy or curly, it's likely you have the 2c hair type.
The probability of the parents having a child with curly hair is 3/4, as shown in the Punnett square below: A Punnett square for the cross of two heterozygous parents is shown.
We believe one of the reasons is that super-straight hair — also known as type 1a hair — is so rare. In fact, it's the rarest hair type. Only 2% of the world's population has 1a hair. It's mostly found in people of Asian descent.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Your Fifties
Throughout menopause, your hair's texture changes. It often happens around the age of 51 and might be the reason why your hair will change from curly to straight.
Can Curly Hair Go Straight If You Cut It? While getting a cut can dramatically change the look and feel of your curls. But don't worry, cutting curly hair won't make it straight. If you ever notice that your curls appear looser right after your cut, it may be because of the way it was cut.
A lot of parents think that if they cut their kids' curly hair, the curls will “go away” or that the stylist will “cut the curl off” which is not exactly true. A haircut cannot eliminate true natural curl – because curls begin at the hair follicle.
As we move into adulthood and then older, the hair again changes, becoming finer again in our 40s and 50s. All of these changes are genetically programmed. “Hair changes every five to seven years,” said Christo of the Christo Fifth Avenue Salon and creator of the Curlisto line of hair products.
