How to reverse grey hair?

Reversing grey hair isn't straightforward, but there are some approaches to address hair health and hair loss, which might indirectly impact greying.

1. Increasing Blood Flow to the Scalp: Treatments that enhance blood flow can support hair health. This includes using Minoxidil and scalp massages, which are designed to boost blood flow, supplying nutrients and oxygen to hair stem cells. Low-dose tadalafil can also increase blood flow and help maintain existing hair 1.

2. Topical Caffeine: Caffeine can be applied topically to stimulate hair growth by suppressing PDE and increasing IGF One. This method can be as effective as Minoxidil without some of its side effects. However, simply drinking more caffeine won't achieve this effect; it's the topical application that's key 2.

These methods mainly focus on hair growth and health rather than reversing greying directly. For targeted strategies on reversing grey hair, consult a healthcare professional for personalized advice.

There are several treatments discussed by Andrew Huberman that may help with hair loss and potentially benefit grey hair if the underlying issue is addressed. Here are some options:

1. Combination Treatments:

   • Microneedling and Finasteride: This combination can lead to significant hair regrowth. It's effective even for those who have lost a considerable amount of hair 1.
   • Microneedling and Minoxidil: Combining these treatments can recover regions of the scalp that are mostly or completely bald. However, minoxidil needs to be continued for life to maintain the gained hair 2.

2. Topical Treatments:

   • Ketoconazole Shampoo: Using a shampoo with at least 2% concentration of ketoconazole can be helpful. This shampoo should be used two to four times a week, with a scalp contact time of three to five minutes to ensure it reaches the follicles 3.

3. Caffeine:

   • Topical Caffeine: Applying caffeine topically can be as effective as minoxidil in stimulating hair growth. However, it should be used a few times a week rather than daily 4.

4. Mechanical Stimuli:

   • Scalp Massages: Although direct data supporting this for hair growth is limited, it's a simple method to try alongside other treatments 1.

These treatments are primarily focused on hair regrowth and health. There is no definitive treatment mentioned specifically for reversing grey hair. For personalized advice, consulting a healthcare professional is recommended.

To use caffeine for hair growth or to halt hair loss, you should apply topical caffeine ointments or creams to the scalp. Here's how you can proceed based on advice from Andrew Huberman:

1. Topical Application: Apply caffeine ointment or cream directly to the scalp about three times a week. This topical application can be as effective as minoxidil in promoting hair growth but without the side effects like lowering blood pressure or increasing prolactin levels 1.

2. Consistency: Building a consistent routine is essential. Aim to include this application a few times weekly rather than daily to see optimal results 1.

3. Understand Limitations: Keep in mind that both minoxidil and caffeine are primarily used to prevent further hair loss rather than promote new robust hair growth. They work by maintaining the existing hair and reducing naturally occurring cell death in hair follicles 2.

4. Consider Effectiveness: Because caffeine also stimulates IGF One indirectly by suppressing Pde, it is a promising option with fewer side effects. However, be aware that the concentrations of caffeine in various products can vary 1 2.

Following this approach should aid in maintaining and potentially slightly increasing hair growth. However, consult with a healthcare provider for personalized advice.
