Coarse hair can be quite a challenge to manage. It’s not always easy to style, often resists styling, is prone to dryness, and sometimes excessive frizziness. Many owners of this hair type struggle with unruly strands that constantly require additional care. This is why keratin straightening has become one of the most popular treatments for coarse hair. But which keratin should you choose to achieve perfectly smooth, silky, and healthy hair? Let’s explore this question in more detail.

Features of Coarse Hair

Coarse hair has its unique characteristics that influence the choice of care products and straightening procedures. Some of these features include:

  • Dense structure. Each strand is thick and strong, which makes it difficult for care products to penetrate.
  • Dryness and brittleness. Coarse hair often doesn’t receive enough natural oil from the scalp, making it dry and prone to damage.
  • Resistance to styling. This hair doesn’t always hold its shape well and is difficult to style. If styled, it may easily change its structure when exposed to moisture, becoming frizzy and unruly.
  • Frizz and unruliness. Due to the porous nature of the hair, it may absorb moisture from the air, causing it to curl and tangle. This feature is most pronounced during transitional seasons when the weather is particularly humid.

Coarse hair can be either straight or curly. However, many women with straight hair find that their strands become wavy when exposed to moisture.

Which Keratin is Suitable for Coarse Hair?

To achieve the maximum effect from keratin straightening, it’s important to choose products that address the specific needs of coarse hair. A good choice would be products with:

  • High concentration of active ingredients. Coarse hair requires a more potent composition that deeply penetrates the hair shaft and smooths it. Keratin with a high content of proteins and amino acids is best suited for this type of hair.
  • Presence of nourishing and moisturizing components. Since coarse hair tends to be dry, it’s essential that the keratin composition includes beneficial oils (such as argan and macadamia oils) that deeply moisturize the strands and add shine. Other important ingredients can include collagen and amino acids, which help make the hair more elastic.
  • Long-lasting effect. Coarse hair has a strong structure, so for a long-lasting straightening effect, choose keratin with high heat resistance and durability (from 4 to 6 months).

It’s not worth spending time searching for keratin without formaldehyde. Currently, all effective keratin straightening products contain either formaldehyde or its derivatives. These ingredients ensure the effectiveness of the procedure. However, it’s still advisable to choose products from reputable brands with a strong reputation.

Care After Keratin Straightening

Keratin straightening provides a long-lasting effect. However, its duration depends on many factors—proper product selection, professional execution of the procedure, and, of course, proper aftercare. Generally, to prolong the effect, professionals recommend:

  • using sulfate-free shampoos (if the scalp allows);
  • regularly moisturizing the hair with masks and oils;
  • avoiding frequent heat styling;
  • protecting the hair from excess moisture and sun.
