The difference

between fine, thin

and thinning hair


Plus, how to help hair be thicker and fuller with more volume

Dealing with thin hair or thinning hair? The journey to thicker, fuller hair can often feel arduous. We understand how hard it can be to get to the root of your hair care concerns and pick the perfect regimen. That’s why we formulated our invati advanced system with ultimate volume and thickening in mind.


Understanding naturally fine or thin hair vs. thinning hair


Fine hair: Defines your hair’s texture and strand diameter or thickness. Hair textures can be fine, medium or thick.

Thin hair: Describes the density and amount of individual hair follicles you have, no matter the diameter and thickness of each strand. You can have fine hair with thick density, and your hair may still lack volume simply because your hair texture is fine and delicate.

Thinning hair: Hair shedding or loss affects all genders, more than some might realize. In fact, more than 50% of women1 will experience a noticeable loss of hair versus 70% of men2 at some point in their lives. Thinning hair can be caused by a variety of factors, including:



Each hair strand is in one of three growth phases at any time and eventually sheds from the follicle. Dr. Jodi LoGerfo, Doctor of Nursing Practice, Dermatology at Orentreich Medical Group, says, “It’s completely normal to lose 50-100, even 150 hairs a day, but it all depends on how much hair you have to begin with.”


Dr. Jodi explains that many individuals face an intensified amount of hair shedding following episodes of acute stress. When we’re under stress, the levels of the stress hormone cortisol in the body increase, which can interrupt the growth of the hair follicle. Find healthy ways to deal with the stress in your life and prioritize getting a full night of sleep.

“Your hair follicles have high cell turnover and a very vigorous metabolism, so they need nutrients to sustain their growth,” says Dr. Jodi. Any excessive caloric or nutritional deficiency can cause structural defects in the hair follicle and hair loss. The key is eating a balanced, healthy diet with protein, fatty acids, vitamins and minerals.

Those who have had a change in health status may also experience an imbalance in their hair growth cycle, resulting in increased shedding. This type of loss is called telogen effluvium and can last 4-6 months after an illness. “With this type of hair loss, it’s not permanent and never results in complete baldness,” says Dr. Jodi.

How you style your hair can cause excess hair shedding and hair loss. Dr. Jodi points out that very tight ponytails, braids and even hair extensions can damage the hair follicle and lead to hair thinning. This type of hair loss is called traction alopecia and results from persistent pulling and weight on the hair follicles.

Along with tight hairstyles, how you brush, style and dry hair can lead to breakage and hair shedding. “Combing wet hair can extend already thin hair to its breaking point,” says Dr. Jodi. Having a gentle approach and using products that strengthen fragile or thinning hair are key in reducing hair shedding due to styling.
