TLDR Bleaching and combing damage hair's surface and mechanical properties.

The study demonstrated that chemical (bleaching) and mechanical (combing) treatments significantly altered the nanoscale surface properties of human hair, including surface roughness, mechanical stiffness, adhesion properties, and surface potential. These changes were consistent with previously observed effects at the macroscopic fiber-level scale, as shown through advanced imaging modes of atomic force microscopy.

community Low-Dose Oral Minoxidil Does Not Significantly Affect BP

in Minoxidil 178 upvotes 11 months ago

Low-dose oral minoxidil is used for hair loss and does not significantly affect blood pressure but may increase heart rate and cause hypotensive symptoms. Some users experience side effects like palpitations and shortness of breath, while others find it effective; topical minoxidil with tretinoin is also considered.

community Why don’t more people use hair fibers?

in Product 526 upvotes 2 weeks ago

Hair fibers can effectively cover thinning hair when used with minoxidil and hairspray but require daily application and can be inconvenient in certain conditions. Some users prefer treatments like finasteride, dutasteride, microneedling, or wigs due to the maintenance and limitations of hair fibers.

community FYI - Dont use topical minox if you have pets

in Research/Science 304 upvotes 7 months ago

Minoxidil is harmful to pets, especially cats, if they contact it. Users recommend switching to oral minoxidil or taking precautions like washing hands and using head coverings to prevent exposure.

community Minoxidil killed my cat - It was just a few licks - Please be super careful with your pets

in Minoxidil 424 upvotes 2 years ago

In this conversation, people discussed how Minoxidil and Finasteride can be toxic to cats if ingested. It was highlighted that even when being careful with application, there is still a risk of poisoning due to the potential for contact between fur/hair and the substances.
