Hi Equel - the photos are a bit blurry, but my impression is that it's not too early. You still have full coverage, but it looks a bit thin and sad already (no offence). My guess is that you are a defuse thinner, and that thinning-out process will continue. Most guys prefer to make the transition to a hair system discreetly, without other people picking it up. If you take action now you should be able to do that before people start to think of you as bald. It is easier to finesse a change from thin hair to thick healthy hair than it is from slick bald to nonbald.
