In search of help and advices (18M)

My current hair situation :

I feel like my hair is thinning, and my hairline is either maturing or balding, I feel like I lack density. My scalp is always red (I try to wash my hair less now) and it itches me sometimes. My dad has localized baldness (my uncle from my mom’s side doesn’t have that). I’m blond and I want my hair to stay as blond as before while improving my hair density and prevent loss (I don’t wanna be bald even when I’m 70 years old lmao)

What I’m doing :

I saw a study saying scalp massage could help against hair loss . So I’m doing some scalp massage, I also take vitamin D supplements on days I don’t have enough sunlight (which is basically always except in July/August)

What I think of doing but I have doubts :

Using Minoxidil 5% (specifically the Mylan version sold in France since I’m French) to stimulate hair growth and slow hair loss.
But, I read that this may darken my hair and I am looking for ways to maintain my blonde color
I was thinking about using a dermaroller to enhance the absorption of Minoxidil and improve blood circulation to the scalp (please confirm if this is the case)

I would love any advices or anything, I’m really interested, my hair is beautiful and I wanna keep my blond and curly hair forever you know

Thanks for reading everything

min is a good option for hair growth and you can use it with a dermaroller to boost results. Microneedling can enhance absorption. Hair darkening isn’t common, but watch how your hair reacts. Redness and itchiness could be sebderm, so try ketoconazole shampoo and consider CBD oil with MCT. For more info, check out The Beginner’s Guide. Good luck!
