Worried about hair thinning after a perm, will hair loss treatments be effective?

Perhaps because I get perms frequently, I am very worried because I can notice my hair thinning as I get older. These days, various hair loss treatment I heard that it exists, and I am curious about the actual extent of its effectiveness. Especially hair loss treatment I have seen many reviews stating that satisfaction is high if you follow the recommended frequency and take it consistently, but I also hear that the effects vary greatly from person to person, so it is difficult to make a decision easily.

In many reviews hair loss treatment The advantages include improved hair thickness and density, which can be maintained for a certain period. However, the cost is a burden, which is causing me more hesitation. If I undergo the procedure, I would like to know how long the results last and whether the satisfaction is sufficient compared to the cost.

If you, like me, have both hair damage from perms and thinning hair due to age, which hair loss treatment I would like to hear the opinions of those with experience on whether this is suitable and if there are definite advantages when considering the cost.
