What are the effects of using an ice pack to cool down the scalp?

I have M-shaped hair loss....
I have a lot of interest in hair loss, so I looked up some related information. 

Many people seem curious about the close relationship between hair loss and scalp heat, and how to use ice packs to resolve it.

If there is excessive heat in the scalp, the blood supply around the hair follicles becomes inefficient,
It is already a widely known fact that hair loss symptoms, such as hair thinning and falling out easily, can worsen.
Therefore, many people expect convenience and immediate effects,
Use the method of wrapping an ice pack in a towel and placing it directly on the scalp, and
They say this method is definitely effective at temporarily and quickly and powerfully lowering the heat of the scalp~~~^^

However, if you apply an ice pack at too low a temperature directly, the scalp rapidly contracts and expands,
On the contrary, it may irritate the scalp or further hinder blood flow, potentially producing a counterproductive effect,
It is said that risks such as freezing burns cannot be ignored.

Therefore, experts recommend rather than direct cold compresses
Using a fan with cool air or shampooing with lukewarm water and rinsing with cold water,
Or, they advise that using a hair tonic with a cooling effect is a more stable and gentle method~~~^^

Above all, scalp heat is stress, dietary habits, Since it is often caused by complex factors such as imbalances in body rhythm,
Rather than relying solely on temporary cooling therapy
Having healthy lifestyle habits along with sufficient rest is
Fundamentally lower scalp heat
I think this could be the most effective and long-term way to prevent hair loss!!!

When using ice packs, caution is required as much as there are advantages, so please make a careful judgment, and
It is advisable to approach this from multiple angles to resolve the root cause.
I think it will be a great help in maintaining scalp health.
I hope you keep this in mind and take good care of your hair~~~^^
