Пусть фен и шумит, без него длинная чёлка сохнет слишком долго.

Here пусть does not mean a command like let.

In this sentence, пусть is being used in a concessive sense, something like:

• granted,
• even if,
• it may be true that

So Пусть фен и шумит... means something like:

• The hair dryer may be noisy, but...
• Granted that the hair dryer is noisy, ...
• Even though the hair dryer is noisy, ...

This is a very common Russian pattern.

Not really. In this pattern, и is part of the concessive structure.

So пусть ... и ... often works together to mean:

• even though ...
• granted that ...

Here, и does not simply mean and in the normal coordinating sense. It helps create the feeling of concession:

• Пусть фен и шумит, ... = The hair dryer may be noisy, but...

A very close parallel is:

• Хотя фен и шумит, ...

So yes, и is important here, but it is not just a plain and.

Yes, they are very close.

• Хотя фен и шумит... = Although the hair dryer is noisy...
• Пусть фен и шумит... = Granted that the hair dryer is noisy... / Even if it is noisy...

The difference is mostly in nuance:

• хотя is the more direct, standard although
• пусть can sound a bit more like I admit that this is true, but it doesn’t change my point

So in this sentence, пусть gives a sense like:

• Sure, the hair dryer is noisy, but without it...

Because без requires the genitive case.

So:

• он = he/it
• after без, it becomes него

Since фен is masculine, the pronoun referring to it is он, and after без you get:

• без него = without it

You could also say:

• без фена

That would also be correct. Using без него simply avoids repeating фен.

This happens with certain Russian pronouns after prepositions.

Compare:

• его = him / it
• у него = at his place / with him
• без него = without him / without it
• для него = for him / for it

That extra н is normal after many prepositions. So без него is exactly what you should expect.

That is a very common thing for English speakers to notice.

In Russian, чёлка is usually treated as a singular noun. It refers to the hairstyle/section of hair at the front.

So:

• длинная чёлка = long bangs or a long fringe

This is one of those places where Russian and English package the idea differently:

• American English often uses plural bangs
• British English often uses singular fringe
• Russian uses singular чёлка

So the singular here is completely normal.

It is in the nominative case because it is the subject of сохнет.

Breakdown:

• чёлка = feminine singular nominative
• длинная agrees with it: feminine singular nominative
• сохнет = dries / is drying

So the structure is:

• длинная чёлка сохнет = long bangs dry / are drying

Сохнет is from сохнуть, meaning to dry or to be drying.

It works very naturally here for a general statement:

• без него длинная чёлка сохнет слишком долго = without it, long bangs take too long to dry

You could also hear высыхает, from высыхать, which often emphasizes drying out completely. But сохнет is simpler and very natural in everyday speech.

So:

• сохнуть = basic to dry
• высыхать = to dry out / dry completely

In this sentence, сохнет is a good ordinary choice.

Because Russian often uses the present tense for general truths, habits, and regular situations.

So сохнет here means something like:

• dries
• takes time to dry
• is slow to dry

It is not necessarily talking about one specific moment right now. It can describe a general situation:

• Without a hair dryer, long bangs dry too slowly / take too long to dry.

That is very normal Russian usage.

It literally means too long.

In context:

• сохнет слишком долго = takes too long to dry

So долго describes the duration of the drying process, and слишком adds the idea of excessively.

Very literally:

• dries for too long

More natural English:

• takes too long to dry

Yes, Russian word order is flexible, but this order is natural and expressive.

The sentence starts with the concession:

• Пусть фен и шумит, ...
• Granted, the hair dryer is noisy, but...

Then it moves to the main point:

• без него длинная чёлка сохнет слишком долго
• without it, long bangs take too long to dry

Starting with без него in the second clause highlights the contrast:

• yes, it’s noisy — but without it...

Other word orders are possible, but this version sounds smooth and natural.

Because the sentence has two parts:

1. a concessive clause: Пусть фен и шумит
2. the main clause: без него длинная чёлка сохнет слишком долго

Russian separates these with a comma, just as English would separate:

• Granted, the hair dryer is noisy, but without it, long bangs take too long to dry.

So the comma is standard punctuation here.
