Textured Thick Hair

Hairdresser thinning out hair with a razor
Q: When having thick hair and you go and get it textured, will your thick hair never grow back? I used to have really thick hair. When I was around 15 years old the stylist textured my hair.
Since then, now I’m 25, my hair isn’t thick anymore. I tried cutting my hair to shoulder length to see if it would grow thick again. Once you texture thick hair, done wrong or right, will or can it grow back to how it was?

A: This is a really common question. No, texturizing hair cannot affect the amount of hair (density) on one’s head or the thickness of the structure, (whether you have thick or thin hair), in any way. Theoretically, your hair should be able to grow back without a qualm.
But that doesn’t by any means mean that it will grow back to its former thickness. It depends a lot on the technique that was used to thin your hair out. Many stylists like to use a stylist-razor to thin hair out and texturize it. This can be an awesome method, especially for texturizing results, if you know what you’re doing and as long as your razor is kept very sharp and is maintained well. If not sharp or maintained, the razor technique will cause the hair to split at the tips, meaning excessive irreversible breakage, sometimes from roots to tip.
Thinning out of the hair also means that the tips of all the hair are more exposed to heat and damage done by elements such as sun, wind and water. When hair is not thinned out and all one length, the ends all hang at the same length, meaning that each strand is protected by those surrounding it. There is a much bigger surface amount of hair that absorbs heat from styling techniques, and from the elements such as the sun, sea and wind; all of which can do considerable damage to hair.
Thus, thinning hair out too much can cause the ends to continuously break off, which would make it seem to you as if your hair has been permanently thinned out by the stylist. Also remember that most people experiment with extensive heat techniques (flat iron, curling tong and hair dryer), and coloring (color, bleach, highlights etc.) between the age of 15 and 24. This means that hair struggles to grow long, thick and healthy during this phase in any case.
Then you also have to take into account that hair thins out as we age. The structure (the diameter of your hair shaft), tends to become thinner as you age, as well as the density (the amount of hair you have per quare inch of scalp).
You can do a number of things to encourage your hair to grow out thicker, healthier and longer though. Drink a daily vitamin supplement that includes all the vitamins and minerals needed for healthy nails and hair. The best supplements concerning this are usually the vitamin supplements that are prescribed to pregnant women. Always use a heat protection product before you apply any heat to the hair, and use a good quality shampoo and conditioner to nourish the hair.
Treat your hair with immense care when it is wet, as this is when the hair is most vulnerable. Use a weekly hydration mask to hydrate and nourish your hair to help it grow longer and healthier.
