Caffeine and Dry Hair: Does Your Coffee Habit Contribute to Dryness?

When the scalp is not receiving enough oils or sebum from the sebaceous gland your hair and scalp can become dry. The sebaceous gland is responsible for luster and shine in your hair. When oil is under-produced, dry hair and scalp are the result. Many factors can contribute to dry hair, including dehydration.

Diuretic

• Consuming too much caffeine may cause your scalp and hair to become dry because caffeine is a diuretic. You will urinate a lot after drinking caffeine and if you don't replenish those fluids with a non-diuretic type fluid, your body---including your hair and scalp and skin---loses moisture, according to 4-men.org.

General Damage

• Womenfitness.net notes that excessive caffeine consumption can damage hair in general as can a diet that is deficient in minerals and vitamins.

On the Other Hand

• Moderate consumption of caffeine is not considered detrimental to the hair and scalp, explains Hairparlor.com, pointing out that caffeine creams are available in Germany and are used to treat male pattern baldness with good results. The key may be moderation. Drink caffeine products in moderation should help you avoid dehydration.
