✅ Answer: Please consider the following narrations:

1⃣عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْحَجَّاجِ قَالَ: سَأَلْتُ أَبَا إِبْرَاهِیمَ عَنِ الْجَارِیَةِ الَّتِی لَمْ تُدْرِکْ مَتَی یَنْبَغِی لَهَا أَنْ تُغَطِّیَ رَأْسَهَا مِمَّنْ لَیْسَ بَیْنَهَا وَ بَیْنَهُ مَحْرَمٌ وَ مَتَی یَجِبُ عَلَیْهَا أَنْ تُقَنِّعَ رَأْسَهَا لِلصَّلَاةِ قَالَ لَا تُغَطِّی رَأْسَهَا حَتَّی تَحْرُمَ عَلَیْهَا الصَّلَاةُ.

📚 Al-Kafi, vol. 5, p. 533

Abdulrahman ibn Hajjaj said: I asked Imam Kazim (peace be upon him) about a girl who has not yet reached puberty. From what point is it appropriate for her to cover her hair from non-mahrams? And from what point is it obligatory for her to wear a headscarf (khimar) and cover her head for prayer? The Imam replied: She does not cover her head until prayer becomes forbidden to her (i.e., when she begins menstruation)!

2⃣عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِی نَصْرٍ عَنِ الرِّضَا قَالَ: یُؤْخَذُ الْغُلَامُ بِالصَّلَاةِ وَ هُوَ ابْنُ سَبْعِ سِنِینَ وَ لَا تُغَطِّی الْمَرْأَةُ شَعْرَهَا مِنْهُ حَتَّی یَحْتَلِمَ.

📚 Al-Faqih, vol. 3, p. 436

Imam Reza (peace be upon him) said: A boy is instructed to pray at the age of seven, and a woman does not need to cover her hair from him until he experiences a wet dream (ihtilam).

3⃣عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِیسَی عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِی نَصْرٍ عَنِ الرِّضَا قَالَ: لَا تُغَطِّی الْمَرْأَةُ رَأْسَهَا مِنَ الْغُلَامِ حَتَّی یَبْلُغَ الْغُلَامُ.

📚 Qurb al-Isnad, p. 170

Imam Reza (peace be upon him) said: A woman does not cover her head from a boy until he reaches puberty.

✅ Based on the above and other narrations, a woman is obligated to cover her hair from a boy once he reaches puberty and experiences ihtilam (nocturnal emission).

Similarly, once a girl begins menstruation and reaches puberty, it becomes obligatory for her to fully cover her hair from non-mahram men.

✅ Please also consider the following two narrations:

4⃣عن أبي عبداللَّه قال: إِذَا بَلَغَ الْغُلَامُ أَشُدَّهُ ثَلَاثَ عَشْرَةَ سَنَةً و دَخَلَ الْأَرْبَعَ عَشْرَةَ سَنَةً وَجَبَ عَلَيْهِ ما وَجَبَ عَلَى الْمُحْتَلِمِينَ احْتَلَمَ أَمْ لَمْ يَحْتَلِمْ وَ كُتِبَتْ عَلَيْهِ السَّيِّئَاتُ و كُتِبَتْ لَهُ الْحَسَنَاتُ و جَازَ لَهُ كُلُّ شَيْءٍ مِنْ مَالِه إِلَّا أَنْ يَكُونَ ضَعِيفاً أَوْ سَفِيهاً

📚 Al-Khisal, p. 495

Imam Sadiq (peace be upon him) said: When a boy reaches the age of maturity and puberty — which is at 13 lunar years and entering the 14th — everything that is obligatory on one who experiences ihtilam becomes obligatory on him, whether he has experienced ihtilam or not. Sins and good deeds are recorded for him, and all financial matters become permissible for him, unless he is weak-minded or foolish.

5⃣عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبِي عَبْدِ اللَّه قَالَ: حَدُّ بُلُوغِ الْمَرْأَةِ تِسْعُ سِنِينَ

📚 Al-Khisal, p. 421, narration 17

Imam Sadiq (peace be upon him) said: The age of puberty for a girl is 9 lunar years!

✅ Based on the above narrations, when a boy completes his 13th lunar year, all the religious obligations of a pubescent boy apply to him, even if he has not experienced ihtilam. Therefore, such a boy must avoid looking at the hair of non-mahram women.

Likewise, a girl who has completed her 9th lunar year is considered to have reached puberty, even if she has not menstruated, and therefore must fully cover her hair from non-mahram men.
