Does Cornstarch Cause Hair Loss

Does Cornstarch Cause Hair Loss?

Cornstarch is a common kitchen ingredient used as a thickening agent in various foods and as a natural deodorant or dry shampoo. Some people believe that using cornstarch on the hair can lead to hair loss, but is there any scientific evidence to support this claim?

The Science Behind Hair Loss

Hair loss, also known as alopecia, can have various causes, including genetics, hormonal imbalances, medical conditions, and certain medications. It is a complex process involving the interaction of multiple factors that affect the hair’s growth cycle.

Cornstarch and Hair Loss

There is no scientific evidence to suggest that using cornstarch as a hair care product directly causes hair loss. Cornstarch is an inert substance that does not contain any ingredients known to harm hair follicles or interfere with hair growth. When applied to the hair, cornstarch acts as a physical barrier, absorbing excess oil and moisture, which can leave the hair looking and feeling cleaner. However, there are some potential drawbacks to using cornstarch on the hair:

  • Clogs Hair Follicles: Excessive use of cornstarch can lead to the accumulation of product residue on the scalp, potentially clogging hair follicles and hindering hair growth.

  • Dries Out Hair: Cornstarch can absorb moisture from the hair, which can lead to dryness and breakage.

  • Can Cause Irritation: In some cases, cornstarch can cause scalp irritation, especially if the individual has sensitive skin.

  • Temporary Hair Loss: If cornstarch is not thoroughly rinsed out of the hair, it can leave behind a buildup that makes the hair appear thinner and may lead to temporary shedding. This is not true hair loss, as the hair follicles are not damaged.


Based on the available evidence, there is no direct link between using cornstarch and permanent hair loss. However, excessive use, improper application, or individual sensitivities may contribute to temporary hair issues such as dryness, breakage, and scalp irritation. It is essential to maintain proper hair care practices, including regular shampooing, conditioning, and using products suitable for your hair type and scalp health. If you experience persistent hair loss or scalp problems, consulting a dermatologist or hair care professional for proper diagnosis and treatment is recommended.
