Physical effects of styling techniques on the hair structure?

Heat styling

* Heat damage: Heat styling can damage the hair shaft, making it weaker and more prone to breakage. This is especially true for high heat settings and prolonged use.

* Dryness: Heat styling can also dry out the hair, making it more brittle and prone to tangles.

* Split ends: Heat styling can cause the ends of the hair to split, making it look frizzy and unkempt.

Chemical styling

* Chemical damage: Chemical styling, such as perming, coloring, and relaxing, can damage the hair shaft by altering its chemical structure. This can make the hair weaker, more brittle, and more prone to breakage.

* Dryness: Chemical styling can also dry out the hair, making it more brittle and prone to tangles.

* Scalp irritation: Chemical styling can irritate the scalp, causing itching, redness, and flaking.

Mechanical styling

* Mechanical damage: Mechanical styling, such as brushing, combing, and pulling, can damage the hair shaft by causing it to break or split. This is especially true for wet hair, which is more fragile.

* Tangles: Mechanical styling can also cause the hair to tangle, making it difficult to brush and style.

* Hair loss: Excessive mechanical styling can lead to hair loss, especially if it is done too tightly or too often.
