This one is complicated for me

It's okay. Just comment or two:

A shade redundant; either one or the other okay but not both

Okay but (a) assumes the fella you're addressing is already aware of the difficulty and (b) "...bad quality..." is also redundant. So in most cases I think we'd say "…that a bad shampoo…"

Also just a hair redundant (forgive pun, Ara). I'd have writ, "... has faded the (his?) hair …"

A little wordy if not ever-so-slightlhy redundant. Maybe just "…left of the part"

Thus (standing behind him) you can see that a bad shampoo has faded his hair left of the part

I see.... The construction is always made so complex by me......

Yea Ara I've noted a tendency of the ESL to excessive wordiness

Though your determination is impressive

You can see that the poor quality shampoo has caused the hair to fade from the parting towards the left hand side.

It is obvious that the poor quality of the shampoo has caused.....('of the' is optional)


And always use 'you' instead of 'u'.

When the majority of people read 'u', they tend to think that the writer is either lazy or a spotty youth who has not paid attention in class.

It may be trendy and modern, but nearly always tends to leave a bad impression. Some may come here and disagree (one in particular), but believe me, most people will think 'lazy'.

Stupid ignorant bolshie unpleasant or pretentious, I think.
But maybe that's overstating it.
Maybe just ignorant.

Thanks for your advise I'm just sooooo used to it

Advice.
