How Keratin Treatments Affect Thin and Thinning Hair

Smooth hair doesn't have to fall flat.

For those of us with fine hair, smoothing products are a double-edged sword. Yes, they do help us keep frizz, a.k.a. public enemy no. 1, at bay, but a lot of the times, the payoff is substantially limper-looking hair—something us fine-haired types are not really willing to risk. This Catch 22 then becomes too much of a headache, so looking for keratin treatment for thin hair just falls off our list of priorities.

But guess what? Turns out there’s a way we can actually have our cake and hair flip it too. Read on to learn about keratin treatment for thin hair and get inspired to care for your hair type at home:

Damaged hair can cause hair to thin.

First things first, what is a keratin treatment? Keratin is a protein naturally found in your hair, skin, and nails, and when added to your regular hair care regimen as an ingredient, it can serve as a sort of protection against damage. Keratin has the ability to both repair and protect, so it can help you rewind damage that’s been done. It can also guard against future trouble by reinforcing proteins in the hair shaft lost by heat, overstyling, or chemical processing.

The truth is, keratin treatments come in many different forms: There are in-salon professional treatments, keratin-infused shampoos and conditioners, and of course, keratin-based styling products. While many people do love the silky smooth benefits of an in-salon professional treatment, not everyone is a candidate for one. Those with thin or thinning hair might find that the treatment can either be too harsh on their thin strands or flatten them, thereby making the appearance of their thinning hair more noticeable.

At-Home Keratin Treatment for Thin Hair

For those who would prefer an at-home solution geared towards thin or thinning hair, wash with TRESemmé Keratin Smooth Shampoo and Conditioner. This duo is great for controlling frizz without weighing down hair. It’s formulated with hydrating Moroccan Oil that softens and smoothens, yes, but also with a lighter after-feel.

If your strands are particularly parched, you can also treat yourself with Love Beauty and Planet Smooth and Serene Argan Oil & Lavender Leave-In Smoothie Cream to help smooth them back to their less-porous state.

For when you need a bit more polish—say, on date nights—include a few drops of TRESemmé Keratin Smooth Shine Serum into your blow-dry regimen too. Look into products with a lightweight oil. These will help give you that salon sleekness without weighing down thin or thinning hair.

So, What Causes Thinning Hair?

Shedding is a normal part of life; no matter what hair type, length, and texture you have, you will experience hair shedding at some point. Everyone loses strands on a daily basis. A normal amount of hair loss is considered to be “approximately 50 to 150 hairs daily,” according to Unilever’s Peter Bailey, Global Technical Manager for Hair Care.

Shedding can be attributed to the hair growth cycle which revolves around four key stages. Anagen (the growing phase), catagen (the transition phase), telogen (the resting phase), and exogen (the shedding phase). After the shedding stage, the hair follicle goes back into the growing phase, completing the cycle. When the number of strands in the telogen phase increases and the number of hairs in the anagen stage decreases, this is what leads to thinner-looking hair.

If you’re experiencing thinning hair, there are a number of reasons why it may be happening. There’s no universal answer to why your hair might appear to be thinning. Below are three top reasons why people experience thinning hair:

Age & Genetics

Both your age and genetics can determine how your hair cycle functions and, as such, can affect the anagen and exogen phases which will lead to hair loss. According to Peter, “It’s common that the anagen (growing) phase in your hair cycle will decrease in length over time, so the hair may become weaker and thinner after each cycle as you get older.”

Hormonal Changes

Our hormones are constantly changing, especially when you’ve gone through a major transformation such as a pregnancy or menopause. The change in hormones in your body after giving birth can lead to changes in your hair cycle. We recommend that you visit a medical professional for a clear diagnosis.

Hair Damage

If your hair is shedding or breaking easily, you may want to look into your current hair care routine. How you towel-dry, brush, or style your locks can all make a difference to your overall hair health. So be gentle with your locks. After washing, blot hair softly with a micro-fiber towel to absorb moisture from your hair without damaging the strands.

No matter what the reason is for your hair starting to thin, consider a keratin treatment for thin hair to give your strands a boost of smoothness and shine. Good luck!
